See the question was so trivial that you actually missed it :)
The problem is that the docs are filtered (which is is great) but the stats
(BasicStats) aren't, i.e. the stats have been calculated over the whole index
and not just a selected set of documents. For example:
Filter filter = new FieldCacheTermsFilter("QNO", queryNumber);
searcher.search(qq, filter, collector);
....
stats.getNumberOfDocuments();
I only want to consider certain docs per query. The filter achieves that in
terms of matching and the returned the results. However, the calculated score
for each document has been calculated using the stats over the whole index and
not just the filtered documents. Is there a way to calculate the stats only
over the filtered documents?
I hope the problem is a bit clearer now.
Thank you.
