Release Notes: This new stable version brings lots of new features. It is now possible to create and manage scripts able to drive a browser with Selenium. The named entity recognition module has been finalized. The new 1.5 REST API has also been fully completed. Some bugs have been fixed: binary indexation does not fail anymore when using XML Load and the URL tag, and the highlighted XML attribute is now set on snippets nodes in Search API. Some other minor enhancements have been implemented, like the ability to choose different weight for phrase queries or term queries in the "Query (fields)" type of query.
Release Notes: Many bugs have been fixed. Spaces in URLs are correctly handled by the crawl API, and the HTTP connector of Tomcat uses the UTF-8 charset by default. Some external libraries have been upgraded. The deletion API now returns the number of deleted documents. The new MAPI messager parser can index offline Outlook messages. The REST crawler has been improved by integrating a callback mechanism.
Release Notes: This is the first beta release. This version is already pretty stable and used in several production environments. Index optimization is no longer required. Both file and Web crawlers are updated in realtime. The new search request includes new min, max, and count functions using collapsing. The REST crawler can index data available as a RESTful Web service using a JSON path.
Release Notes: This is the fourth and probably last developer release. This version has been fully repackaged, and the setup is easier than ever. New APIs are provided to insert patterns (exclusion and inclusion) in the Web crawler. Downloads of compressed sitemaps are now supported.
Release Notes: A RESTFul Web service and a new REST crawler were added. All existing features have been dramatically improved. The build system is now based on Maven. A Ruby client library is now available.
