Jack Krupansky commented on SOLR-5160:
--------------------------------------
In truth, a more-like-this feature should have two modes: 1) Discovery mode, to
broaden the search or increase recall (OR), and 2) Refinement mode, to narrow
the search or increase precision (AND).
> MoreLikeThis (MLT) - New Optional Params - mlt.operator & mlt.sort

> Key: SOLR-5160
> URL: https://issues.apache.org/jira/browse/SOLR-5160
> Project: Solr
> Issue Type: Improvement
> Components: MoreLikeThis
> Reporter: Kranti Parisa
> Priority: Minor
> Labels: features
> Original Estimate: 24h
> Remaining Estimate: 24h

> It seems that when we pass multiple field names with mlt.fl parameter, it is
> ORing them to find the MLT documents.
> Is there a way to specify AND operator? Means if mlt.fl=language,year, then
> we should return back the MLT documents which has language AND year field
> values as same as the main query result document.
> http://localhost:8180/solr/mltCore/mlt?q=id:111111111&wt=json&mlt=true&mlt.fl=language,year&fl=*,score&mlt.mindf=0&mlt.mintf=0&mlt.match.include=false
> The above query should return those documents whose field values (language,
> year) are exactly matching with the document id:111111111.
> Is this possible thru any config or param? If not, I think it's worth having
> as a feature because we don't know the values of those fields to apply as FQ.
> was looking at the code and found that it is hard coded to Occur.SHOULD in
> MoreLikeThisQuery.
> I customized the code to pass a new parameter mlt.operator=AND/OR based on
> that it computes the MLT documents. Default operator is set to OR.
> And I also want to have mlt.sort option, So I will be trying for that as well.
> Do you guys think, we should make this part of the MLT feature?
> Please share your ideas. I can submit this change.
