Adrien Grand updated LUCENE-8059:
---------------------------------
Attachment: LUCENE-8059.patch
Here is a patch:
- It adds a {{trackTotalHits}} parameter to the TopFieldCollector factory
methods
- totalHits is approximated when collection is early-terminated
- EarlyTerminatingSortingCollector is removed (or rather moved to Solr which
used this class in a way that made it hard to cut over to TopFieldCollector)
IndexSearcher still always performs a full collection for now. My goal here was
just to make early termination easier to use. We might be able to
simplify/improve based on the output of the discussion at LUCENE-8060 but I
feel like this change is already a step in the right direction. In particular
it is now easier to use early termination with pagination.
