Came across a JIRA filed for pooling IndexReaders https://issues.apache.org/jira/browse/LUCENE-2297
For every commit/delete/update cycle IndexWriter opens a bunch of SegmentReaders, does the job & closes it. Does the JIRA aim to re-use the SegmentReaders for all commit-cycles till they are finally closed (after a merge, rollback, iw.close() etc...) ? Also, we use DirectoryReader.open(dir) construct for searching. Is the SegmentReader instances associated with this different from that IndexWriter's & thus have different life-cycle? Could someone please help in understanding this readerPooling option -- Ravi
