Adrien Grand updated LUCENE-5979:
---------------------------------
Attachment: LUCENE-5979.patch
Here is a simple patch. I imagine the idea of {{firstFilterDoc < 100}} was to
use random-access when the filter matches more than 1% of documents, so I
translated it to {{filterCost * 100 > maxDoc}}.
> Use the cost API instead of a heuristic on the first document in
> FilteredQuery to decide on whether to use random access

> Now that some major filters such as TermsFilter and
> MultiTermQueryWrapperFilter return DocIdSets that have a better cost, we
> should switch to the cost API.
