                 Key: SOLR-2351
                 URL: https://issues.apache.org/jira/browse/SOLR-2351
             Project: Solr
          Issue Type: Improvement
          Components: MoreLikeThis
    Affects Versions: 1.5
            Reporter: Amit Nithian
            Priority: Minor
             Fix For: 1.5, 1.3


Currently the MLT component doesn't accept filter queries specified on the URL which my application
needed (I needed to restrict similar results by a lat/long bounding box). This patch also
attempts to solve the issue of allowing the boost functions of the dismax to be used in the
MLT component by using the query object created by the QueryComponent to OR with the query
created by the MLT as part of the final query. In a blank dismax query with no query/phrase
clauses, this works although a separate BF definition/parsing would be ideal.
