All Implemented Interfaces:

Serializable, Cloneable

Deprecated. Use TermRangeQuery for term ranges or NumericRangeQuery for numeric ranges instead. This class will be removed in Lucene 3.0.

public class ConstantScoreRangeQuery
extends TermRangeQuery

A range query that returns a constant score equal to its boost for all documents in the exclusive range of terms.

It does not have an upper bound on the number of clauses covered in the range.

This query matches the documents looking for terms that fall into the supplied range according to String.compareTo(String). It is not intended for numerical ranges, use NumericRangeQuery instead.

This query is hardwired to MultiTermQuery.CONSTANT_SCORE_AUTO_REWRITE_DEFAULT. If you want to change this, use TermRangeQuery instead.
