Examples of org.apache.lucene.search.TermRangeQuery

org.apache.lucene.search.TermRangeQuery
A Query that matches documents within an range of terms.
This query matches the documents looking for terms that fall into the supplied range according to {@link Byte#compareTo(Byte)}. It is not intended for numerical ranges; use {@link NumericRangeQuery} instead.
This query uses the {@link MultiTermQuery#CONSTANT_SCORE_AUTO_REWRITE_DEFAULT}rewrite method. @since 2.9
