I think the iterator *is* the equivalent of the Matcher as you've 
described it - a Scorer without the scores used once by a single thread 
to iterate across a set of doc ids.

Could be (QueryFilter or FilteredQuery? - can never remember which wraps 
which), but RangeFilter and TermsFilter are examples of Filters with 
their own criteria (a range and a list of terms respectively). There may 
be others out there...
