-</li>
-<li>
-<p>Analyzing/FuzzySuggester now allow to record arbitrary byte[] as a payload. The suggesters

- a query "i " will no longer suggest "Isla de Muerta" for example.</p>

-<p>New SearcherTaxonomyManager manages near-real-time reopens of both IndexSearcher and

-<h3 id="lucene-42-release-highlights">Lucene 4.2 Release Highlights:</h3>
-<ul>
-<li>
-<p>Lucene 4.2 has a new default codec (Lucene42Codec) with a more
- efficient docvalues format (sorted bytes in FST, less addressing
- overhead, improved numeric compression) and smaller term
- vectors (LZ4-compressed terms dictionaries and payloads, delta-encoded
- positions and offsets using blocks of packed integers).</p>
-</li>
-<li>
-<p>Doc values external and codec API and implementations have been
- simplified: the codec is no longer responsible for buffering doc
- values; the numerous types have been consolidated down to only
- three (NUMERIC, BINARY, SORTED); PerFieldDocValuesFormat lets you
- set a different format for each field, and the doc values and FieldCache
- APIs were unified.</p>
-</li>
-<li>
-<p>Significant refactoring and performance enhancements to the facet
- module, resulting in overall ~3.8X speedup in one case (single Date
- field faceting).</p>
-</li>
-<li>
-<p>DrillDownQuery in the facet module now supports multi-select.</p>
-</li>
-<li>
-<p>A new DrillSideways class enables counting facet labels and counts
- for both hits and near-misses in a single query. See
- <a href="http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html">http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html</a></p>
-</li>
-<li>
-<p>An additional docvalues type (SORTED_SET) was added that supports multiple
- values.</p>
-</li>
-<li>
-<p>FSTs are a bit smaller, and the FST package supports FSTs over 2GB
- in size.</p>
-</li>
-<li>
-<p>A new LiveFieldValues class lets you get live or real-time values
- for any indexed doc / field. See <a href="http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html">http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html</a></p>

-release for a full list of details.</p>
-<h3 id="lucene-41-release-highlights">Lucene 4.1 Release Highlights:</h3>
-<ul>
-<li>
-<p>Lucene 4.1 has a new default codec (Lucene41Codec) based on the
- previously-experimental "Block" indexing format for improved
- performance, but also incorporating the functionality of "Appending"
- and "Pulsing".</p>
-</li>
-<li>
-<p>The default codec incorporates the optimization of Pulsing: terms
- that appear in only one document (such as primary key/id fields) just
- store the document id in the term dictionary instead of a pointer to
- this document id in a separate file.</p>
-</li>
-<li>
-<p>The default codec incorporates an efficient compressed stored fields
- implementation that compresses chunks of documents together with LZ4.
- (see
- <a href="http://blog.jpountz.net/post/33247161884/efficient-compressed-stored-fields-with-lucene">http://blog.jpountz.net/post/33247161884/efficient-compressed-stored-fields-with-lucene</a>)</p>
-</li>
-<li>
-<p>Lucene no longer seeks when writing files (all fields are written in
- an append-only way). This means it works by default with append-only
- streams, hdfs, etc.</p>
-</li>
-<li>
-<p>New suggest implementations: AnalyzingSuggester, where the underlying
- form (computed from a lucene Analyzer) used for suggestions is
- separate from the returned text (see
- <a href="http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html">http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html</a>),
- and FuzzySuggester, which additionally allows for inexact matching on
- the input.</p>
-</li>
-<li>
-<p>Near-realtime support was added to the facet module.
- (see <a href="http://shaierera.blogspot.com/2012/11/lucene-facets-part-1.html">http://shaierera.blogspot.com/2012/11/lucene-facets-part-1.html</a>)</p>
-</li>
-<li>
-<p>New Highlighter (postingshighlighter) added to the highlighter
- module. (see
- <a href="http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html">http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html</a>)</p>
-</li>
-<li>
-<p>Added FilterStrategy to FilteredQuery for more flexibility in
- filtered query execution.</p>
-</li>
-<li>
-<p>Added CommonTermsQuery to speed up queries with very highly frequent
- terms. Term frequencies are efficiently detected at query time - no
- index time preparation required.</p>
-</li>
-<li>
-<p>Several bugfixes and optimizations since the 4.0 release.</p>

-<h3 id="highlights-of-the-solr-release-include_2">Highlights of the Solr release include:</h3>
-<ul>
-<li>
-<p>Solr indexes and transaction logs may stored in HDFS with full read/write
- capability.</p>
-</li>
-<li>
-<p>Schemaless mode: Added support for a mode that requires no up-front schema
- modifications, in which previously unknown fields' types are guessed based
- on the values in added/updated documents, and are then added to the schema
- prior to processing the update. Note that the below-described features
- are also useful independently from schemaless mode operation. </p>
-<ul>
-<li>New Parse{Date,Integer,Long,Float,Double,Boolean}UpdateProcessorFactory
- classes parse/guess the field value class for String-valued and unknown
- fields.</li>
-<li>New AddSchemaFieldsUpdateProcessor: Automatically add new fields to the
- schema when adding/updating documents with unknown fields. Custom rules
- map field value class(es) to schema fieldTypes.</li>
-<li>A new schemaless mode example configuration, using the above-described
- field-value-class-guessing and unknown-field-schema-addition features,
- is provided at solr/example/example-schemaless/.</li>
-</ul>
-</li>
-<li>
-<p>Core Discovery mode: A new solr.xml format which does not store core
- information, but instead searches for files named 'core.properties' in
- the filesystem which tell Solr all the details about that core. The main
- example and the schemaless example both use this new format.</p>

-<h3 id="highlights-of-the-lucene-release-include_6">Highlights of the Lucene release include:</h3>
-<ul>
-<li>
-<p>Lucene 4.2 has a new default codec (Lucene42Codec) with a more
- efficient docvalues format (sorted bytes in FST, less addressing
- overhead, improved numeric compression) and smaller term
- vectors (LZ4-compressed terms dictionaries and payloads, delta-encoded
- positions and offsets using blocks of packed integers).</p>
-</li>
-<li>
-<p>Doc values external and codec API and implementations have been
- simplified: the codec is no longer responsible for buffering doc
- values; the numerous types have been consolidated down to only
- three (NUMERIC, BINARY, SORTED); PerFieldDocValuesFormat lets you
- set a different format for each field, and the doc values and FieldCache
- APIs were unified.</p>
-</li>
-<li>
-<p>Significant refactoring and performance enhancements to the facet
- module, resulting in overall ~3.8X speedup in one case (single Date
- field faceting).</p>
-</li>
-<li>
-<p>DrillDownQuery in the facet module now supports multi-select.</p>
-</li>
-<li>
-<p>A new DrillSideways class enables counting facet labels and counts
- for both hits and near-misses in a single query. See
- <a href="http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html">http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html</a></p>
-</li>
-<li>
-<p>An additional docvalues type (SORTED_SET) was added that supports multiple
- values.</p>
-</li>
-<li>
-<p>FSTs are a bit smaller, and the FST package supports FSTs over 2GB
- in size.</p>
-</li>
-<li>
-<p>A new LiveFieldValues class lets you get live or real-time values
- for any indexed doc / field. See <a href="http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html">http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html</a></p>
-</li>
-<li>
-<p>Added a new classification module.</p>
-</li>
-<li>
-<p>Various bugfixes and optimizations since the 4.1 release.</p>
-</li>
-</ul>
-<h3 id="highlights-of-the-solr-release-include_6">Highlights of the Solr release include:</h3>
-<ul>
-<li>
-<p>A read side REST API for the schema. Always wanted to introspect the schema over http?
- Now you can. Looks like the write side will be coming next.</p>
-</li>
-<li>
-<p>DocValues have been integrated into Solr. DocValues can be loaded up a lot faster than
- the field cache and can also use different compression algorithms as well as in RAM or
- on Disk representations. Faceting, sorting, and function queries all get to benefit.
- How about the OS handling faceting and sorting caches off heap? No more tuning 60 gigabyte heaps?
- How about a snappy new per segment DocValues faceting method? Improved numeric faceting? Sweet.</p>
-</li>
-<li>
-<p>Collection Aliasing. Got time based data? Want to re-index in a temporary collection
- and then swap it into production? Done. Stay tuned for Shard Aliasing.</p>
-</li>
-<li>
-<p>Collection API responses. The collections API was still very new in 4.0, and while it
- improved a fair bit in 4.1, responses were certainly needed, but missed the cut off.
- Initially, we made the decision to make the Collection API super fault tolerant, which
- made responses tougher to do. No one wants to hunt through logs files to see how things
- turned out. Done in 4.2.</p>
-</li>
-<li>
-<p>Interact with any collection on any node. Until 4.2, you could only interact with a node
- in your cluster if it hosted at least one replica of the collection you wanted to query/update.
- No longer - query any node, whether it has a piece of your intended collection or not and
- get a proxied response.</p>
-</li>
-<li>
-<p>Allow custom shard names so that new host addresses can take over for retired shards.
- Working on Amazon without elastic ips? This is for you.</p>
-</li>
-<li>
-<p>Lucene 4.2 optimizations such as compressed term vectors.</p>

-<ul>
-<li>
-<p>Lucene 4.1 has a new default codec (Lucene41Codec) based on the
- previously-experimental "Block" indexing format for improved
- performance, but also incorporating the functionality of "Appending"
- and "Pulsing".</p>
-</li>
-<li>
-<p>The default codec incorporates the optimization of Pulsing: terms
- that appear in only one document (such as primary key/id fields) just
- store the document id in the term dictionary instead of a pointer to
- this document id in a separate file.</p>
-</li>
-<li>
-<p>The default codec incorporates an efficient compressed stored fields
- implementation that compresses chunks of documents together with LZ4.

-</li>
-<li>
-<p>Lucene no longer seeks when writing files (all fields are written in
- an append-only way). This means it works by default with append-only
- streams, hdfs, etc.</p>
-</li>
-<li>
-<p>New suggest implementations: AnalyzingSuggester, where the underlying
- form (computed from a lucene Analyzer) used for suggestions is
- separate from the returned text (see
- <a href="http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html">http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html</a>),
- and FuzzySuggester, which additionally allows for inexact matching on
- the input.</p>
-</li>
-<li>
-<p>Near-realtime support was added to the facet module.

-</li>
-<li>
-<p>Added FilterStrategy to FilteredQuery for more flexibility in
- filtered query execution.</p>
-</li>
-<li>
-<p>Added CommonTermsQuery to speed up queries with very highly frequent
- terms. Term frequencies are efficiently detected at query time - no
- index time preparation required.</p>

-<ul>
-<li>Simple multi-tenancy through enhanced document routing:<ul>
-<li>The "compositeId" router is the default for collections with hash
- based routing (i.e. when numShards=N is specified on collection
- creation).</li>
-<li>Documents with ids sharing the same domain/prefix, e.g.
- 'customerB!', will be routed to the same shard, allowing for
- efficient querying. At query time, one can specify a "shard.keys"
- parameter that lists the domains, e.g. 'shard.keys=customerB!', and
- controls what shards the query is routed to.</li>
-<li>Collections that do not specify numShards at collection creation
- time use custom sharding and default to the "implicit" router.
- Document updates received by a shard will be indexed to that shard,
- unless a "<em>shard</em>" parameter or document field names a different
- shard.</li>
-</ul>
-</li>
-<li>Short circuiting for distributed search if a request only needs
- to query a single shard.</li>
-<li>Allow creating more than one shard per instance with the Collection
- API.</li>
-<li>Allow access to the collections API through CloudSolrServer without
- referencing an existing collection.</li>
-<li>Collection API: Support for specifying a list of Solr addresses to

-<h4 id="new-features">New features:</h4>
-<ul>
-<li>The majority of Solr's features, including replication, now work with

-<li>Indexed term offsets, specifiable via a 'storeOffsetsWithPositions'
- flag on field definitions in the schema. Useful for highlighters.</li>
-<li>Solr QParsers may now be directly invoked in the lucene query syntax
- via localParams and without the <em>query</em> magic field hack.
- Example: foo AND {!term f=myfield v=$qq}</li>
-<li>Solr now parses request parameters (from URL or sent with POST using
- content-type application/x-www-form-urlencoded) in its dispatcher code.
- It no longer relies on special configuration settings in Tomcat or other
- web containers to enable UTF-8 encoding, which is mandatory for correct
- Solr behaviour. Solr now works out of the box with e.g. Tomcat, JBoss,...</li>
-<li>Directory IO rate limiting based on the IO context.</li>
-<li>Distributed search support for MoreLikeThis.</li>
-<li>Multi-core: On-demand core loading and LRU-based core unloading after
- reaching a user-specified maximum number.</li>
-<li>The new Solr 4 spatial fields now work with the {!geofilt} and {!bbox}
- query parsers. The score local-param works too.</li>
-<li>Extra statistics to RequestHandlers - 5 & 15-minute reqs/sec rolling
- averages; median, 75th, 95th, 99th, 99.9th percentile request times.</li>

-<ul>
-<li>Added dynamic (no taxonomy index used) numeric range faceting (see
- <a href="http://blog.mikemccandless.com/2013/05/dynamic-faceting-with-lucene.html">http://blog.mikemccandless.com/2013/05/dynamic-faceting-with-lucene.html</a> )</li>

-<p>FST's Builder can now handle more than 2.1 billion "tail nodes" while
- building a minimal FST.</p>
-</li>
-<li>
-<p>FieldCache Ints and Longs now use bit-packing to save memory. String fields

-<h3 id="highlights-of-the-solr-release-include_2">Highlights of the Solr release include:</h3>
-<ul>
-<li>
-<p>Solr indexes and transaction logs may stored in HDFS with full read/write
- capability.</p>
-</li>
-<li>
-<p>Schemaless mode: Added support for a mode that requires no up-front schema
- modifications, in which previously unknown fields' types are guessed based
- on the values in added/updated documents, and are then added to the schema
- prior to processing the update. Note that the below-described features
- are also useful independently from schemaless mode operation. </p>
-<ul>
-<li>New Parse{Date,Integer,Long,Float,Double,Boolean}UpdateProcessorFactory
- classes parse/guess the field value class for String-valued and unknown
- fields.</li>
-<li>New AddSchemaFieldsUpdateProcessor: Automatically add new fields to the
- schema when adding/updating documents with unknown fields. Custom rules
- map field value class(es) to schema fieldTypes.</li>
-<li>A new schemaless mode example configuration, using the above-described
- field-value-class-guessing and unknown-field-schema-addition features,
- is provided at solr/example/example-schemaless/.</li>
-</ul>
-</li>
-<li>
-<p>Core Discovery mode: A new solr.xml format which does not store core
- information, but instead searches for files named 'core.properties' in
- the filesystem which tell Solr all the details about that core. The main
- example and the schemaless example both use this new format.</p>
-</li>
-<li>
-<p>Schema REST API: Add support for creating copy fields.</p>
-</li>
-<li>
-<p>A merged segment warmer may now be plugged into solrconfig.xml. </p>

-</li>
-<li>
-<p>Added a PUT command to the Solr ZkCli tool.</p>
-</li>
-<li>
-<p>New "deleteshard" collections API that unloads all replicas of a given
- shard and then removes it from the cluster state. It will remove only
- those shards which are INACTIVE or have no range.</p>
-</li>
-<li>
-<p>The Overseer can now optionally assign generic node names so that
- new addresses can host shards without naming confusion.</p>
-</li>
-<li>
-<p>The CSV Update Handler now supports optionally adding the line number/
- row id to a document.</p>

- segments are merged.</p>
-</li>
-<li>
-<p>DocIdSetIterator and Scorer now has a cost API that provides an upper bound

- during query execution or how filters are applied.</p>
-</li>
-<li>
-<p>Analyzing/FuzzySuggester now allow to record arbitrary byte[] as a payload. The suggesters

-<h3 id="highlights-of-the-lucene-release-include_6">Highlights of the Lucene release include:</h3>
-<ul>
-<li>
-<p>Lucene 4.2 has a new default codec (Lucene42Codec) with a more
- efficient docvalues format (sorted bytes in FST, less addressing
- overhead, improved numeric compression) and smaller term
- vectors (LZ4-compressed terms dictionaries and payloads, delta-encoded
- positions and offsets using blocks of packed integers).</p>
-</li>
-<li>
-<p>Doc values external and codec API and implementations have been
- simplified: the codec is no longer responsible for buffering doc
- values; the numerous types have been consolidated down to only
- three (NUMERIC, BINARY, SORTED); PerFieldDocValuesFormat lets you
- set a different format for each field, and the doc values and FieldCache
- APIs were unified.</p>
-</li>
-<li>
-<p>Significant refactoring and performance enhancements to the facet
- module, resulting in overall ~3.8X speedup in one case (single Date
- field faceting).</p>
-</li>
-<li>
-<p>DrillDownQuery in the facet module now supports multi-select.</p>
-</li>
-<li>
-<p>A new DrillSideways class enables counting facet labels and counts
- for both hits and near-misses in a single query. See
- <a href="http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html">http://blog.mikemccandless.com/2013/02/drill-sideways-faceting-with-lucene.html</a></p>
-</li>
-<li>
-<p>An additional docvalues type (SORTED_SET) was added that supports multiple
- values.</p>
-</li>
-<li>
-<p>FSTs are a bit smaller, and the FST package supports FSTs over 2GB
- in size.</p>
-</li>
-<li>
-<p>A new LiveFieldValues class lets you get live or real-time values
- for any indexed doc / field. See <a href="http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html">http://blog.mikemccandless.com/2013/01/getting-real-time-field-values-in-lucene.html</a></p>
-</li>
-<li>
-<p>Added a new classification module.</p>
-</li>
-<li>
-<p>Various bugfixes and optimizations since the 4.1 release.</p>
-</li>
-</ul>
-<h3 id="highlights-of-the-solr-release-include_6">Highlights of the Solr release include:</h3>
-<ul>
-<li>
-<p>A read side REST API for the schema. Always wanted to introspect the schema over http?
- Now you can. Looks like the write side will be coming next.</p>
-</li>
-<li>
-<p>DocValues have been integrated into Solr. DocValues can be loaded up a lot faster than
- the field cache and can also use different compression algorithms as well as in RAM or
- on Disk representations. Faceting, sorting, and function queries all get to benefit.
- How about the OS handling faceting and sorting caches off heap? No more tuning 60 gigabyte heaps?
- How about a snappy new per segment DocValues faceting method? Improved numeric faceting? Sweet.</p>
-</li>
-<li>
-<p>Collection Aliasing. Got time based data? Want to re-index in a temporary collection
- and then swap it into production? Done. Stay tuned for Shard Aliasing.</p>
-</li>
-<li>
-<p>Collection API responses. The collections API was still very new in 4.0, and while it
- improved a fair bit in 4.1, responses were certainly needed, but missed the cut off.
- Initially, we made the decision to make the Collection API super fault tolerant, which
- made responses tougher to do. No one wants to hunt through logs files to see how things
- turned out. Done in 4.2.</p>
-</li>
-<li>
-<p>Interact with any collection on any node. Until 4.2, you could only interact with a node
- in your cluster if it hosted at least one replica of the collection you wanted to query/update.
- No longer - query any node, whether it has a piece of your intended collection or not and
- get a proxied response.</p>
-</li>

-<h3 id="highlights-of-the-lucene-release-include_7">Highlights of the Lucene release include:</h3>
-<ul>
-<li>
-<p>Lucene 4.1 has a new default codec (Lucene41Codec) based on the
- previously-experimental "Block" indexing format for improved
- performance, but also incorporating the functionality of "Appending"
- and "Pulsing".</p>
-</li>
-<li>
-<p>The default codec incorporates the optimization of Pulsing: terms
- that appear in only one document (such as primary key/id fields) just
- store the document id in the term dictionary instead of a pointer to
- this document id in a separate file.</p>
-</li>
-<li>
-<p>The default codec incorporates an efficient compressed stored fields
- implementation that compresses chunks of documents together with LZ4.
- (see
- <a href="http://blog.jpountz.net/post/33247161884/efficient-compressed-stored-fields-with-lucene">http://blog.jpountz.net/post/33247161884/efficient-compressed-stored-fields-with-lucene</a>)</p>
-</li>
-<li>
-<p>Lucene no longer seeks when writing files (all fields are written in
- an append-only way). This means it works by default with append-only
- streams, hdfs, etc.</p>
-</li>
-<li>
-<p>New suggest implementations: AnalyzingSuggester, where the underlying
- form (computed from a lucene Analyzer) used for suggestions is
- separate from the returned text (see
- <a href="http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html">http://blog.mikemccandless.com/2012/09/lucenes-new-analyzing-suggester.html</a>),
- and FuzzySuggester, which additionally allows for inexact matching on
- the input.</p>
-</li>
-<li>
-<p>Near-realtime support was added to the facet module.
- (see <a href="http://shaierera.blogspot.com/2012/11/lucene-facets-part-1.html">http://shaierera.blogspot.com/2012/11/lucene-facets-part-1.html</a>)</p>
-</li>
-<li>
-<p>New Highlighter (postingshighlighter) added to the highlighter
- module. (see
- <a href="http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html">http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html</a>)</p>
-</li>
-<li>
-<p>Added FilterStrategy to FilteredQuery for more flexibility in
- filtered query execution.</p>
-</li>
-<li>
-<p>Added CommonTermsQuery to speed up queries with very highly frequent
- terms. Term frequencies are efficiently detected at query time - no
- index time preparation required.</p>
-</li>
-<li>
-<p>Several bugfixes and optimizations since the 4.0 release.</p>

-<h3 id="highlights-of-the-solr-release-include_7">Highlights of the Solr release include:</h3>
-<h4 id="solrcloud-enhancements-see-httpwikiapacheorgsolrsolrcloud">SolrCloud enhancements (see <a href="http://wiki.apache.org/solr/SolrCloud">http://wiki.apache.org/solr/SolrCloud</a>):</h4>
-<ul>
-<li>Simple multi-tenancy through enhanced document routing:<ul>
-<li>The "compositeId" router is the default for collections with hash
- based routing (i.e. when numShards=N is specified on collection
- creation).</li>
-<li>Documents with ids sharing the same domain/prefix, e.g.
- 'customerB!', will be routed to the same shard, allowing for
- efficient querying. At query time, one can specify a "shard.keys"
- parameter that lists the domains, e.g. 'shard.keys=customerB!', and
- controls what shards the query is routed to.</li>
-<li>Collections that do not specify numShards at collection creation
- time use custom sharding and default to the "implicit" router.
- Document updates received by a shard will be indexed to that shard,
- unless a "<em>shard</em>" parameter or document field names a different
- shard.</li>
-</ul>
-</li>
-<li>Short circuiting for distributed search if a request only needs
- to query a single shard.</li>
-<li>Allow creating more than one shard per instance with the Collection
- API.</li>
-<li>Allow access to the collections API through CloudSolrServer without
- referencing an existing collection.</li>
-<li>Collection API: Support for specifying a list of Solr addresses to
- spread a new collection across.</li>
-<li>New and improved auto host detection strategy.</li>
-<li>Numerous bug fixes and general hardening - it's recommended that all
- Solr 4.0 SolrCloud users upgrade to 4.1.</li>
-</ul>
-<h4 id="new-features">New features:</h4>
-<ul>
-<li>The majority of Solr's features, including replication, now work with
- custom Directory and DirectoryFactory implementations.</li>
-<li>Indexed term offsets, specifiable via a 'storeOffsetsWithPositions'
- flag on field definitions in the schema. Useful for highlighters.</li>
-<li>Solr QParsers may now be directly invoked in the lucene query syntax
- via localParams and without the <em>query</em> magic field hack.
- Example: foo AND {!term f=myfield v=$qq}</li>
-<li>Solr now parses request parameters (from URL or sent with POST using
- content-type application/x-www-form-urlencoded) in its dispatcher code.
- It no longer relies on special configuration settings in Tomcat or other
- web containers to enable UTF-8 encoding, which is mandatory for correct
- Solr behaviour. Solr now works out of the box with e.g. Tomcat, JBoss,...</li>
-<li>Directory IO rate limiting based on the IO context.</li>
-<li>Distributed search support for MoreLikeThis.</li>
-<li>Multi-core: On-demand core loading and LRU-based core unloading after
- reaching a user-specified maximum number.</li>
-<li>The new Solr 4 spatial fields now work with the {!geofilt} and {!bbox}
- query parsers. The score local-param works too.</li>
-<li>Extra statistics to RequestHandlers - 5 & 15-minute reqs/sec rolling
- averages; median, 75th, 95th, 99th, 99.9th percentile request times.</li>
-<li>PostingsHighlighter support (see
- <a href="http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html">http://blog.mikemccandless.com/2012/12/a-new-lucene-highlighter-is-born.html</a>) </li>

-<h4 id="admin-ui-improvements">Admin UI improvements:</h4>
-<ul>
-<li>Internet Explorer is now supported</li>
-<li>Enhanced readability of XML query response display in Query UI</li>
-<li>Many improvements to DataImportHandler UI</li>

-<li>Admin Cores UI now redirects to newly created core details</li>
-<li>Deleted documents are calculated/displayed</li>

-<ul>
-<li>Faster search, in particular for rare terms such as primary key/id
- fields.</li>
-<li>Stored fields are compressed. (See
