if passing a stored document to MoreLikeThisHandler does mlt.mindf=1 exlude the document passed in?

Question

In Solr, I am using the MoreLikeThis handler. I am passing in the unique id of a document that already exists in the index in order to find related documents. Does specifying mlt.mindf=1 include the previously mentioned document? If I want to be sure it exists in at least one document other than the one I pass in, should I set the value of mlt.mindf=2 instead?

Answer 1

That's a fun project your'e doing :D

And your'e correct. You should set the value to 2 if you want to make sure that there is at-least one other document with the same term.

Tip:

• If you're automatically finding related documents,i.e, the relation(term) is not specified by a user, make sure you search for good keywords to find related documents by filtering out unwanted words(use any of the available filters to do this).

• You could also suggest some words(maybe 5,6,..) and use javascript to make something like the Wonder-wheel.

Have fun :)

Answer 2

mindf specifies the minimum document frequency, that is, the minimum number of documents that must include a term for that term to be counted.
