Create a single query suitable for use by all subsearchers (in 1-1

all queries. We handle the common optimization cases of equal
queries and overlapping clauses of boolean OR queries (as generated
by MultiTermQuery.rewrite()).
Be careful overriding this method as queries[0] determines which
method will be called and is not necessarily of the same type as
the other queries.
