Apache Lucene is a high-performance, full-featured text search engine library written entirely in Java.
Apache Lucene is a technology suitable for nearly any application that requires full-text search, especially cross-platform.
Enhancements:
- Many new features, optimizations, and bugfixes have been added since 2.1.0, including "point-in-time" searching over NFS, payloads, function queries, and new APIs for pre-analyzed fields.
- This release includes index format changes that are not readable by older versions.
- It can both read and update older Lucene indexes.
- Adding to an index with an older format will cause it to be converted to the newer format.

Apache Solr is a high performace search server based on Lucene, with XML/HTTP and JSON APIs, hit highlighting, faceted search, caching, replication, and a Web administration interface.
The project is currently under incubation at the Apache Software Foundation.
Instructions for Building Apache Solr
1. Download the J2SE 5.0 JDK (Java Development Kit) or later from http://java.sun.com. You will need the JDK installed, and the %JAVA_HOME%bin directory included on your command path. To test this, issue a "java -version" command from your shell and verify that the Java version is 5.0 or later.
2. Download the Apache Ant binary distribution from http://ant.apache.org. You will need Ant installed and the %ANT_HOME%bin directory included on your command path. To test this, issue a "ant -version" command from your shell and verify that Ant is available.
3. Download the Apache Solr source distribution, linked from the above incubator web site. Expand the distribution to a folder of your choice, e.g. c:solr.
4. Navigate to that folder and issue an "ant" command to see the available options for building, testing, and packaging solr.
Enhancements:
- 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.
