ABOUT MONTYSOLR

MontySolr is the search engine behind Astrophysics Data System (ADS 2.0) - "the world's most complete collection of scholarly content in the physical sciences" - http://ads.harvard.edu/. It is built on top of SOLR (http://lucene.apache.org/solr) but it is not a fork. New features are added as extensions. You can use MontySolr's infrastructure to add new functionality or test patches without duplicating code.

So what is here:

• extremely powerful query parser (equivalent of which you won't find anywhere else)
• second order queries (operators): analytical query operations
• batch processing for long-running tasks
• bitset queries (to search/analyze millions of docs by sending their IDs)
• author name disambiguation
• extensive tokenization rules
• multi-synonym parsing and expansion
• support for Jython
• and of course: the whole configuration of the ADS search engine

In the past MontySolr combined Java with extensions written in C++/Python but now that Jython support for JNI arrived, MontySolr switched to pure Java (April 2014)
