    public class MoreLikeThisQuery

extends org.apache.lucene.search.Query

A simple wrapper for MoreLikeThis for use in scenarios where a Query object is required eg in custom QueryParser extensions. At query.rewrite() time the reader is used to construct the actual MoreLikeThis object and obtain the real Query object.
