Hi!
I am very excited to announce the availability of Apache Solr 4.10 with
RankingAlgorithm 1.5.4.
Solr 4.10.0 with RankingAlgorithm 1.5.4 includes support for complex-lsa.
complex-lsa simulates human language acquisition and recognition (see demo
<http://solr-ra.tgels.org/rankingsearchlsa.jsp> ) and can retrieve
semantically related/hidden relationships between terms, sentences,
paragraphs, chapters, books, images, etc. Three new similarities,
TERM_SIMILARITY, DOCUMENT_SIMILARITY, TERM_DOCUMENT_SIMILARITY enable these
with improved precision. A query for “holy AND ghost” returns jesus/christ
as the top results for the bible corpus with no effort to introduce this
relationship (see demo <http://solr-ra.tgels.org/rankingsearchlsa.jsp> ).
This version adds support for multiple linear algebra libraries.
complex-lsa does a large amount of this calcs so speeding this up should
speed up the retrieval etc. EJML is the fastest if you are using complex-lsa
for a smaller set of documents, while MTJ is faster as your document
collection becomes bigger. MTJ can also use BLAS/LAPACK, etc installed on
your system to further improve performance with native execution. The
performance is similar to a C/C++ application. It can also make use of GPUs
or Intel's mkl library if you have access to it.
RankingAlgorithm 1.5.4 with complex-lsa supports the entire Lucene Query
Syntax , ± and/or boolean/dismax/glob/regular
expression/wildcard/fuzzy/prefix/suffix queries with boosting, etc. This
version increases performance, with increased accuracy and relevance for
Document similarity, fixes problems with phrase queries, Boolean queries,
etc.
You can get more information about complex-lsa and realtime-search
performance from here:

You can download Solr 4.10 with RankingAlgorithm 1.5.4 from here:

Please download and give the new version a try.
