Release Notes:
-----------------------------------------------------------------------------------------
This is Heliosearch v0.03
Heliosearch is forked from Apache Solr and includes the following
additional features:

- Off-Heap Filters to reduce garbage collection pauses and overhead.
http://www.heliosearch.org/off-heap-filters

- Removed the 1024 limit on the number of clauses in a boolean query.
For example: q=id:(doc1 doc2 doc3 doc4 doc5 ... doc2000) will now work
correctly without throwing an exception.

- Deep Paging with cursorMark.  This is not yet in a current release
of Apache Solr, but should be in Solr 4.7

- nCache - the new Off-Heap FieldCache to reduce garbage collection
overhead and accelerate sorting, faceting, and function queries.
