Thanks that helped a lot with the speed!!
I am getting same search results but with different docIds. Is this expected
and OK? Are they just arbitrar numbers
If I changed from
Hits hits = mSearcher.search(query, filter);
To the following
TopDocCollector collector = new TopDocCollector(1000000);
mSearcher.search(query, filter,collector);
hits = collector.topDocs().scoreDocs;
