Examples of org.apache.lucene.search.TermRangeFilter

org.apache.lucene.search.TermRangeFilter
A Filter that restricts search results to a range of term values in a given field.
This filter 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 NumericRangeFilter} instead.
If you construct a large number of range filters with different ranges but on the same field, {@link FieldCacheRangeFilter} may have significantly better performance. @since 2.9

   *             instead. This constructor will be removed in Lucene 4.0.
