Class MoreLikeThisQuery

  • All Implemented Interfaces:

    public class MoreLikeThisQuery
    extends 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.
