mayya-sharipova opened a new pull request #32: URL: https://github.com/apache/lucene/pull/32
1. Add an option to supply a custom leaf sorter for IndexWriter. A DirectoryReader opened from this IndexWriter will have its leaf readers sorted with the provided leaf sorter. This is useful for indices on which it is expected to run many queries with particular sort criteria (e.g. for time-based indices this is usually a descending sort on timestamp). Providing leafSorter allows to speed up early termination for this particular type of sort queries. 2. Add an option to supply a custom sub-readers sorter for BaseCompositeReader. In this case sub-readers will be sorted according to the the provided leafSorter. 3. Add an option to supply a custom leaf sorter for StandardDirectoryReader. The leaf readers of this StandardDirectoryReader will be sorted according to the the provided leaf sorter. -- This is an automated message from the Apache Git Service.
