public class TermRangeQuery extends AutomatonQuery
This query matches the documents looking for terms that fall into the
supplied range according to BytesRef.compareTo(BytesRef)
.
This query uses the MultiTermQuery.CONSTANT_SCORE_REWRITE
rewrite method.

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.)

Typically a query will be equal to another only if it's an instance of
the same class and its document-filtering properties are identical that other
instance. Utility methods are provided for certain repetitive code.equals
