Apache Solr 3.1 发布，开源搜索服务器

Apache Solr 3.1发布了。 它是继Solr 1.4.1发布之后的第一个版本，因为 Solr 与Lucene 版本号同步，因此在版本号上做了个跳跃。

Apache Solr是一个性能强大的，基于 Lucene 的全文搜索的 开源企业级搜索服务器，拥有XML/HTTP,JSON APIs，hit highlighting, faceted search, caching, replication,web管理界面等很多功能，Solr运行在Java servlet容器比如Tomcat中。

Solr 3.1 新亮点包括：

• Numeric range facets (similar to date faceting).
• New spatial search, including spatial filtering, boosting and sorting capabilities.
• Example Velocity driven search UI at http://localhost:8983/solr/browse
• A new faster termvector-based highlighter.
• Extended dismax (edismax) query parser with support for fielded queries, enhanced relevancy, and full lucene syntax support.
• Distributed search support for the Spell check and Terms components.
• Suggester, a fast trie-based autocomplete component.
• Sort results by any function query
• JSON document indexing
• CSV response format
• Apache UIMA integration for metadata extraction.
• Tons of optimizations, bugfixes, and new analysis capabilities via Apache Lucene 3.1
