Subject [jira] [Commented] (LUCENE-8788) Order LeafReaderContexts by Estimated Number Of Hits
Date Tue, 21 May 2019 13:16:00 GMT


Adrien Grand commented on LUCENE-8788:

I think this is definitely worth exploring. It looks like a subset of LUCENE-8727, since
we are only aiming at using fully collected slices here to speed up slices that have not been
collected yet.

> We offer no guarantee on the order in which an IndexSearcher will look at segments during
a search operation. This can be improved for use cases where an engine using Lucene invokes
early termination and uses the partially collected hits. A better model would be if we sorted
segments by the estimated number of hits, thus increasing the probability of the overall relevance
of the returned partial results.
