MoreLikeThis (MLT) - AND operator between the fields
Hi,
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.
Thanks & Regards,

Yes, I will be submitting a patch for mlt.operator parameter.

I don't know enough about MLT to have an opinion one way or the other. But
it's
perfectly fine to open up a JIRA and attach your patch,

I 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.
