Solr is a high performance search server based on Lucene, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a Web administration interface.


This is the first release since graduating from the Apache Incubator. Some of the new features include CSV/delimited-text data loading, time based autocommit, faster faceting, negative filters, a spell-check handler, sounds-like word filters, regex text filters, and more flexible plugins.
