Search MoreLikeThis ID into another collations
Hi!
Im new in Solr, I would like to do a MoreLikeThis search for an ID into
other collections, not only in the collection that owns that ID
Is that posible? do you have an example?
Thank you very much!

Thank you very much for your answers!!
As I said earlier, I am new in Solr and I would like to know if there is any
way to get the list of terms in the document with that ID.
I found that I can add the parameters facet = true and facet.field = TITLE
to return all terms ordered by frequency rather. Is this helpful?
Thank you very much!

Oh, yes, definitely... you can certainly do it yourself.
It would be nice to have a request handler that did the document
"characterization", returning the most significant terms. Then the app could
simply send a request for that to the first collection and then turn it into
a query for the other collection.

I know this can be done, because I did it in Ultraseek. It was the first
feature I wrote, probably around 1997.
Take the most significant terms from the document and turn them into a
query. You can use the tf-idf scores of the terms as weights. I tested my
queries (without weights) from Ultraseek against several WWW search engines
(we used to have a lot more of those). Two test documents that I remember
were the "Yes, Virginia there is a Santa Claus" newspaper column and a Kodak
Tri-X film datasheet. For there first, there are lots of copies on the
internet. For the second, there are (were) lots of similar 400 speed black
and white films. I was an Ilford man, myself.
It worked pretty well.

Do you mean pointing to a document in one collection and retrieving
documents from another collection that are similar to the first document?
Not that I know of.
Sounds like a reasonable Jira request.
But... the too collections would need to be fairly similar overall
themselves, because the characterization of the first document would be
based on terms in that collection, but those terms might not even occur in
the other collection.
