Mark Miller commented on LUCENE-998:
------------------------------------

I think it was understood - it made field cache loading slow because we attempted to enumerate every unique term for all segments from every individual segment. Because term/seg drops log, it was incredibly wasteful. You could try 5,000 terms against each of 5 segments when segments 2-5 may have had 3 terms a piece in them. So I don't think it will be an issue here - we should get a bit better performance with LUCENE-1483 though, because each multi-term query will rewrite against each segment - so you won't have huge boolean queries hitting small segments like before - each multi-term query will 'fit' each segment, rather than one query hits all.

> 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.
