Thanks for sharing this info.
In any case, this is not a problem for me since I have used only the "idea"
to choose between OpenBitSet and SortedViIntList from contrib BooleanFilter,
but I have then implemented it in my own facets manager structure, so I do
not use the "removed" finalResult method.
Meanwhile the choice between SortedVIntList and OpenBitSet
has been removed from the trunk (development version),
that now uses OpenBitSet only:
https://issues.apache.org/jira/browse/LUCENE-1296
In case there is preference to have SortedVIntList used in the
next lucene version (i.e. in cases when

Took a little time to find these classes, they are post-2.4 additions I

I am sorry, but I cannot understand: how can I create a BooleanFilter or a

Thanks for your answer, I did not know about FieldCache.
However, I think
Our implementation of facet search can handle this. Using bitsets for
intersection is not scalable performance wise when index is large.
We are using a compact forwarded index representation in memory for the
counting. Similar to FieldCache idea but more compact.

The first approach is rather limiting when facets number grows.
The "SortedVIntList" approach is similar to field cache. It's better to use
the fieldcache for the facet search, which is the "normal" approach and used

To avoid creating a lot of
Did you look at Solr? It provides faceted search out of the box and is
built on top of Lucene.
