> It would somehow disable itself if the application sets its own static index sort? This is correct. This bit already works on the PR, IndexWriter doesn't check the new method that `OneMerge` got that allows reordering the resulting segment if an index sort is configured in the `IndexWriterConfig`. > It's odd/curious that PKLookup got slower The terms dictionary should be exactly the same, only doc IDs get renumbered. BlockTree optimizes for incremental IDs by storing the delta of a singleton doc ID with the previous doc ID (`termState.singletonDocID += BitUtil.zigZagDecode(l >>> 1);` in `Lucene90PostingsReader`). I wonder that it doesn't only help with storage, but also with lookups since it's stored as a single-byte vInt in the incremental case, but often on a variable number of bytes after reordering. -- This is an automated message from the Apache Git Service.
