+<h1>Apache Solr Release Notes</h1>
+
+<div id="buttons.parent"></div>
+
+<h2>Introduction</h2>
+ <p>Apache Solr is an open source enterprise search server based on the Apache Lucene Java
+search library, with XML/HTTP and JSON APIs, hit highlighting, faceted search,
+caching, replication, and a web administration interface.
+</p>
+ <p>See <a href="http://lucene.apache.org/solr">http://lucene.apache.org/solr</a> for more information.
+</p>
+<h2>Getting Started</h2>
+ <p>You need a Java 1.8 VM or later installed.
+In this release, there is an example Solr server including a bundled
+servlet container in the directory named "example".
+See the Quick Start guide at <a href="http://lucene.apache.org/solr/quickstart.html">http://lucene.apache.org/solr/quickstart.html</a>
+</p>
+<h2><a id="v6.4.0" href="javascript:toggleList('v6.4.0')">Release 6.4.0 </a></h2>
+<ul id="v6.4.0.list">
+ <li>Consult the LUCENE_CHANGES.txt file for additional, low level, changes in this release.
+</li>
+ </li>
+ <li><a id="v6.4.0.versions_of_major_components" href="javascript:toggleList('v6.4.0.versions_of_major_components')">Versions of Major Components</a> (6)
+ <ol id="v6.4.0.versions_of_major_components.list">
+ <li>Apache Tika 1.13
+</li>
+ <li>Carrot2 3.15.0
+</li>
+ <li>Velocity 1.7 and Velocity Tools 2.0
+</li>

+ <h3>Detailed Change List</h3>
+ <li><a id="v6.4.0.upgrade_notes" href="javascript:toggleList('v6.4.0.upgrade_notes')">Upgrade Notes</a> (8)
+ <ol id="v6.4.0.upgrade_notes.list">
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9166">SOLR-9166</a>: Export handler returns zero for numeric fields that are not in the original doc. One
+consequence of this change is that you must be aware that some tuples will not have values if
+there were none in the original document.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-8785">SOLR-8785</a>: Metrics related classes in org.apache.solr.util.stats have been removed in favor of
+the dropwizard metrics library. Any custom plugins using these classes should be changed to use
+the equivalent classes from the metrics library.
+As part of this, the following changes were made to the output of Overseer Status API:
+</li>
+ <li>The "totalTime" metric has been removed because it is no longer supported
+</li>
+ <li>The metrics "75thPctlRequestTime", "95thPctlRequestTime", "99thPctlRequestTime"
+and "999thPctlRequestTime" in Overseer Status API have been renamed to "75thPcRequestTime", "95thPcRequestTime"
+and so on for consistency with stats output in other parts of Solr.
+</li>
+ <li>The metrics "avgRequestsPerMinute", "5minRateRequestsPerMinute" and "15minRateRequestsPerMinute" have been
+replaced by corresponding per-second rates viz. "avgRequestsPerSecond", "5minRateRequestsPerSecond"
+and "15minRateRequestsPerSecond" for consistency with stats output in other parts of Solr.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9708">SOLR-9708</a>: You are encouraged to try out the UnifiedHighlighter by setting hl.method=unified and report feedback. It
+might become the default in 7.0. It's more efficient/faster than the other highlighters, especially compared to the
+original Highlighter. That said, some options aren't supported yet.
+It will get more features in time, especially with your input. See HighlightParams.java
+for a listing of highlight parameters annotated with which highlighters use them.
+hl.useFastVectorHighlighter is now considered deprecated in lieu of hl.method=fastVector.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9712">SOLR-9712</a>: maxWarmingSearchers now defaults to 1, and more importantly commits will now block if this
+limit is exceeded instead of throwing an exception (a good thing). Consequently there is no longer a
+risk in overlapping commits. Nonetheless users should continue to avoid excessive committing. Users are
+advised to remove any pre-existing maxWarmingSearchers entries from their solrconfig.xml files.
+<p/>
+</li>
+ <li><a href="http://issues.apache.org/jira/browse/SOLR-7466">SOLR-7466</a>: complexphrase query parser now supports leading wildcards. Beware of its' possible heaviness.
+Users are encouraged to use ReversedWildcardFilter in index time analysis.
+<p/>
+</li>

+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9681">SOLR-9681</a>: FacetModule / JSON Facet API added the ability to add filters directly to

+ <li><a href="http://issues.apache.org/jira/browse/SOLR-9708">SOLR-9708</a>: Added UnifiedSolrHighlighter, a highlighter adapter for Lucene's UnifiedHighlighter. The adapter is a
+derivative of the PostingsSolrHighlighter, supporting mostly the same parameters with some differences.
+Introduced "hl.method" parameter which can be set to original|fastVector|postings|unified to pick the highlighter at
+runtime without the need to modify solrconfig from the default configuration. hl.useFastVectorHighlighter is now
+considered deprecated in lieu of hl.method=fastVector.

+and create a more efficient query (such as TermsQuery). The solr query parser has been
+changed to use this method when appropriate. The parser also knows when it is being
+used to parse a filter and will create TermsQueries from large lists of normal terms
+or numbers, resulting in a query that will execute faster. This also acts to avoid
+BooleanQuery maximum clause limit. Query parsing itself has also been optimized,
+resulting in less produced garbage and 5-7% better performance.

+ <li>If you use the JSON Facet API (json.facet) with method=stream, you must now set sort='index asc' to get the streaming

+</li>
+ <li>Solr's logging verbosity at the INFO level has been greatly reduced, and

+<p/>
+</li>
+ <li>We are no longer backing up solr.log and solr_gc.log files in date-stamped copies forever. If you relied on
