28 April 2014, Apache Solr™ 4.8.0 available The Lucene PMC is pleased to announce the release of Apache Solr 4.8.0
Solr is the popular, blazing fast, open source NoSQL search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, rich document (e.g., Word, PDF) handling, and geospatial search. Solr is highly scalable, providing fault tolerant distributed search and indexing, and powers the search and navigation features of many of the world's largest internet sites. Solr 4.8.0 is available for immediate download at: http://lucene.apache.org/solr/mirrors-solr-latest-redir.html See the CHANGES.txt file included with the release for a full list of details. Solr 4.8.0 Release Highlights: * Apache Solr now requires Java 7 or greater (recommended is Oracle Java 7 or OpenJDK 7, minimum update 55; earlier versions have known JVM bugs affecting Solr). * Apache Solr is fully compatible with Java 8. * <fields> and <types> tags have been deprecated from schema.xml. There is no longer any reason to keep them in the schema file, they may be safely removed. This allows intermixing of <fieldType>, <field> and <copyField> definitions if desired. * The new {!complexphrase} query parser supports wildcards, ORs etc. inside Phrase Queries. * New Collections API CLUSTERSTATUS action reports the status of collections, shards, and replicas, and also lists collection aliases and cluster properties. * Added managed synonym and stopword filter factories, which enable synonym and stopword lists to be dynamically managed via REST API. * JSON updates now support nested child documents, enabling {!child} and {!parent} block join queries. * Added ExpandComponent to expand results collapsed by the CollapsingQParserPlugin, as well as the parent/child relationship of nested child documents. * Long-running Collections API tasks can now be executed asynchronously; the new REQUESTSTATUS action provides status. * Added a hl.qparser parameter to allow you to define a query parser for hl.q highlight queries. * In Solr single-node mode, cores can now be created using named configsets. * New DocExpirationUpdateProcessorFactory supports computing an expiration date for documents from the "TTL" expression, as well as automatically deleting expired documents on a periodic basis. Solr 4.8.0 also includes many other new features as well as numerous optimizations and bugfixes of the corresponding Apache Lucene release. Please report any feedback to the mailing lists (http://lucene.apache.org/solr/discussion.html) Note: The Apache Software Foundation uses an extensive mirroring network for distributing releases. It is possible that the mirror you are using may not have replicated the release yet. If that is the case, please try another mirror. This also goes for Maven access. ----- Uwe Schindler uschind...@apache.org Apache Lucene PMC Chair / Committer Bremen, Germany http://lucene.apache.org/
