Optimizations
|

|
||||
1. LUCENE-586: TermDocs.skipTo() is now more efficient for multi-segment
|
||||
indexes. This will improve the performance of many types of queries
|
||||
against a non-optimized index. (Andrew Hudson via Yonik Seeley)

2. LUCENE-623: RAMDirectory.close now nulls out its reference to all
|

internal "files", allowing them to be GCed even if references to the
|

RAMDirectory itself still exist. (Nadav Har'El via Chris Hostetter)
|

|
||||
3. LUCENE-629: Compressed fields are no longer uncompressed and recompressed
|

during segment merges (e.g. during indexing or optimizing), thus improving

performance . (Michael Busch via Otis Gospodnetic)

certain level have been accumulated. This increases indexing performance

in the presence of deleted docs or partially full segments as well as

enabling future optimizations. (Ning Li, Yonik Seeley)
