API 更新:

  1. LUCENE-8051 : LevensteinDistance renamed to LevenshteinDistance. 

    (Pulak Ghosh via Adrien Grand)

  2. LUCENE-8099 : Deprecate CustomScoreQuery, BoostedQuery and BoostingQuery. Users should instead use FunctionScoreQuery, possibly combined with a lucene expression 

    (Alan Woodward)

  3. LUCENE-8104 : Remove facets module compile-time dependency on queries 

    (Alan Woodward)

  4. LUCENE-8145 : UnifiedHighlighter now uses a unitary OffsetsEnum rather than a list of enums 

新特性:

  1. LUCENE-2899 : Add new module analysis/opennlp, with analysis components to perform tokenization, part-of-speech tagging, lemmatization and phrase chunking by invoking the corresponding OpenNLP tools. Named entity recognition is also provided as a Solr update request processor. 

    (Lance Norskog, Grant Ingersoll, Joern Kottmann, Em, Kai Gülzau, Rene Nederhand, Robert Muir, Steven Bower, Steve Rowe)

  2. LUCENE-8126 : Add new spatial prefix tree (SPT) based on google S2 geometry. It can only be used currently with Geo3D spatial context and it provides improvements on indexing time for non-points shapes and on query performance.
