Apache Lucene 8.4.0 released, Lucene is a full-text search engine architecture that provides a complete query engine and index engine, part of the text analysis engine. The purpose is to provide a simple-to-use software developer kit for convenient full-text search functions in the target system, or as a basis to establish a complete full-text search engine.
The new version of the highlights include:
- LatLonShape now supports "CONTAINS" relationship that may contain a query to find all indexes shape shape
- Concurrent search by allowing collectors to share information across threads, to more effectively hit skip non-competitive, so that it becomes more efficient
- Faster on the dense node FST Find
- It can now be decoded using the SIMD instruction postings
- LRUQueryCache includes new heuristics to prevent buffer delay too much influence
- LatLonShape build a more efficient tree, is expected to improve search speed
- BaseDirectoryReader can more effectively hide a subset of the document reader view
- Index at the top of the tree now BKD external memory heap by MMapDirectory
- Simple query interval highlighting support
- More than time, it may interrupt the reading DocValues
