Solr MoreLikeThisComponent: Return similarity value for result documents

I execute a SOLR search and return related documents using the MoreLikeThisComponent (passing mlt=true and related parameters via URL). How can I get the similarity value for the similar documents?

Solution

  • You can get the score field back. Add the score field to the fl parameter.

    If you wanna normalize, add the match_include parameter, and normalize the scores against the one of the document you submitted.

    See http://docs.lucidworks.com/display/solr/MoreLikeThis for more details on each parameters.
