It is a technology suitable for nearly any > application that requires full-text search, especially cross-platform. > > This release contains numerous bug fixes, optimizations, and improvements, > some of which are highlighted below. The release is available for immediate > download at: > http://lucene.apache.org/core/mirrors-core-latest-redir.html > > See the CHANGES.txt file included with the release for a full list of details. > > Lucene 4.3 Release Highlights: > > * Significant performance improvements for minShouldMatch BooleanQuery > due to > skipping resulting in up to 4000% faster queries. > > * A new SortingAtomicReader which allows sorting an index based on a sort > criteria (e.g. > a numeric DocValues field), as well as SortingMergePolicy which sorts > documents before > segments are merged. > > * DocIdSetIterator and Scorer now has a cost API that provides an upper > bound > of the number of documents the iterator might match. This API allows > optimisation > during query execution or how filters are applied. > > * Analyzing/FuzzySuggester now allow to record arbitrary byte[] as a > payload. The suggesters > also use an ending offset to determine whether the last token was finished > or not, so that > a query "i " will no longer suggest "Isla de Muerta" for example. > > * Lucene Spatial Module can now search for indexed shapes by Within, > Contains, and Disjoint > relationships, in addition to typical Intersects. > > * PostingsHighlighter now allows custom passage scores, per-field > BreakIterators and has been > detached from TopDocs. Additionally, subclasses can override where string > values for highlighting > are pulled from alternatively to stored fields. > > * New SearcherTaxonomyManager manages near-real-time reopens of both > IndexSearcher and > TaxonomyReader (for faceting). > > * Added new facet method to the facet module to compute facet counts > using SortedSetDocValuesField, without a separate taxonomy index. > > - DrillSideways class, for computing sideways facet counts, is now more > flexible: it allows more > than one FacetRequest per dimension and now allows drilling down on > dimensions that do not have a facet request. > > - Various bugfixes and optimizations since the 4.2.1 release. > > Please read CHANGES.txt for a full list of new features. > > Please report any feedback to the mailing lists > (http://lucene.apache.org/core/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. > > Happy searching, > Lucene/Solr developers > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [email protected] For additional > commands, e-mail: [email protected] --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
