Solr is a high performance full-text search server based on Apache Lucene, written in Java5, and easily extensible through plugins written in Java. Documents are added to a search collection via XML over HTTP. The collection is queried via HTTP to receive an XML response (or alternately JSON, Python or Ruby text formats). Major features include: * A powerful data schema to define fields, types, and configure text analysis * External configuration via xml * Faceted search * Hit highlighting * Flexible advanced caching * Index replication for high availability * A web admin interface Some of the new features in 1.2 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. Apache Solr 1.2 can be downloaded from http://www.apache.org/dyn/closer.cgi/lucene/solr/ Thank you for your interest in Apache Solr! -- The Apache Solr Team...

Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java. It is suitable for nearly any application that requires full-text search, especially cross-platform.

This is mostly a bugfix and cleanup release from release 1.9.1. Deprecated 1.x features have now been removed. Any code that compiles against Lucene 1.9.1 without deprecation warnings should work without further changes with any 2.x release.

For more information about this release, please read CHANGES.txt.
