----------------------------------------------------------------
This patch should fix the problem.
However, the implementation of the bits() method is so inefficient that it
might actually motivate users to avoid it.
The patch also contains a docIdSetToCache() method with the DocIdSet and the
IndexReader as arguments, as discussed at LUCENE-1296.
