TermRangeQuery(String, BytesRef, BytesRef, Boolean, Boolean)

Constructs a query selecting all terms greater/equal than lowerTerm but less/equal than upperTerm.

If an endpoint is null, it is said to be "open". Either or both endpoints may be open. Open endpoints may not be exclusive (you can't select all but the first or last term without explicitly specifying the term to exclude.)
