Examples of org.apache.lucene.search.ConstantScoreRangeQuery

org.apache.lucene.search.ConstantScoreRangeQuery
A range query that returns a constant score equal to its boost for all documents in the range.
It does not have an upper bound on the number of clauses covered in the range.
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.) @author yonik @version $Id: ConstantScoreRangeQuery.java 472959 2006-11-09 16:21:50Z yonik $
