Apache Solr 1.4 finally released

apache_solr_logoFinally, after long delays, Apache Solr version 1.4 is released. The long delay was mainly due to very strict quality standards, which made it necessary to wait until some serious known bugs were dealt with. Also read my previous article on what’s new in this version. Here is the official release statement:

Apache Solr 1.4 has been released and is now available for
public download! http://www.apache.org/dyn/closer.cgi/lucene/solr/

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

Solr is written in Java and runs as a standalone full-text search
server within a servlet container such as Tomcat. Solr uses the
Lucene Java search library at its core for full-text indexing and
search, and has REST-like HTTP/XML and JSON APIs that make it easy
to use from virtually any programming language. Solr’s powerful
external configuration allows it to be tailored to almost any type
of application without Java coding, and it has an extensive plugin
architecture when more advanced customization is required.

New Solr 1.4 features include
- Major performance enhancements in indexing, searching, and
  faceting
- Revamped all-Java index replication that’s simple to configure
  and can replicate config files
- Greatly improved database integration via the DataImportHandler
- Rich document processing (Word, PDF, HTML) via Apache Tika
- Dynamic search results clustering via Carrot2
- Multi-select faceting (support for multiple items in a single
  category to be selected)
- Many powerful query enhancements, including ranges over arbitrary
  functions, and nested queries of different syntaxes
- Many other plugins including Terms for auto-suggest, Statistics,
  TermVectors, Deduplication
