The second approach requires three hits, doesn't it?
(1) TermQuery on start date + sort on document ID
(2) TermQuery on end date + reverse sort on document ID
(3) The actual query with a filter on the above
Would that really be a saving?

You could always construct a BooleanQuery with all the necessary sub-clauses
on an as-needed basis. You can string the sub-clauses together in
arbitrarily complex ways. Be particularly aware that you one of the clauses
of a BooleanQuery may itself be a boolean query, so constructing something

Thanks for the clarification. Let me re-state this and see if I got it
right.
