Michael McCandless commented on LUCENE-998:
-------------------------------------------
Timeout collector is an interesting approach, though it's not great because you
will have spent XXX cpu only to determine you shouldn't have attempted the
query in the first place. Whereas the maxClauseCount spends less CPU deciding
to abort, though it is spooky that multi term queries, when rewriting, use
MutiReader.terms(), which in LUCENE-1483 we found to be disastrously slow in
certain, not fully understood situations.

> BooleanQuery.setMaxClauseCount(int) is static. It does not allow searching in
> multiple indices from different threads using different settings. This
> setting should be probably moved in to the IndexSearcher.
