Michael McCandless commented on LUCENE-4562: -------------------------------------------- That's a cool idea! In the patch in LUCENE-3729 I just do the full lookup and then compare ... but making it incremental (this issue) is a great idea. > Pair-wise FST key comparator by ords > ------------------------------------ > > Key: LUCENE-4562 > URL: https://issues.apache.org/jira/browse/LUCENE-4562 > Project: Lucene - Core > Issue Type: New Feature > Components: core/FSTs > Reporter: David Smiley > Priority: Minor > > It would be useful to have an FST utility method to do a compare() operation > between a key in one FST and a key in a second FST, by ords instead of the > keys. So the input is the ord for FST1 and an ord for FST2 and the output is > -1, 0, 1. The result is the same as if you were to do a Util.getByOutput for > both ords against their respective FSTs then compare the resulting byte > arrays. > The point of this is to speedup LUCENE-3729 further, which impact sorting > across segments. I would be surprised if it doesn't have applicability to > other problems. -- This message is automatically generated by JIRA.
