Solr is the popular, blazing fast, open source NoSQL search platform from the
Apache Lucene project. Its major features include powerful full-text search,
hit highlighting, faceted search, dynamic clustering, database integration,
rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly
scalable, providing fault tolerant distributed search and indexing, and powers
the search and navigation features of many of the world's largest internet
sites.

* Users can now choose compression mode in SchemaCodecFactory
