> this seems promising. I guess the only cost is the increased memory needed because we create the FixedBitSet? Can you say how large this might get in the worst case? @msokolov In https://github.com/apache/lucene/blob/c701a5d9be4d8dc677ea994f8ef5fdd8945760d6/lucene/core/src/java/org/apache/lucene/util/bkd/DocIdsWriter.java#L66-L74 AND https://github.com/apache/lucene/blob/c701a5d9be4d8dc677ea994f8ef5fdd8945760d6/lucene/core/src/java/org/apache/lucene/util/bkd/DocIdsWriter.java#L131-L140 so, i think in `BITSET_IDS` type with `DocBaseBitSetIterator` in max range is about 8192 docids(16 * 512) which FixedBitSet memory is 128 longs. and BKDReaderDocIDSetIterator contains 512 ints -- This is an automated message from the Apache Git Service.
