Examples of org.apache.lucene.search.ConstantScoreQuery

org.apache.lucene.search.ConstantScoreQuery
A query that wraps another query or a filter and simply returns a constant score equal to the query boost for every document that matches the filter or query. For queries it therefore simply strips of all scores and returns a constant one.
