the solr 1.4 book says you can do this.
usages of mlt:
"As a request handler with an external input document: What if you want
similarity results based on something that isn't in the index? A final
option that Solr supports is returning MLT results based on text data
sent to the MLT handler (through HTTP POST). For example, if you were to
send a text file to the handler, then Solr's MLT handler would return
the documents in the index that are most similar to it. This is atypical
but an interesting option nonetheless."
not sure about the details of how though as i haven't used mlt myself.

This is somewhat of an odd use-case for MLT. Basically I'm using it for
near-duplicate detection (I'm not using the built in dup detection for a
variety of reasons). While this might sound like an okay idea, the problem
lies in the order of which things happen. Ideally, duplicate detection would
prevent me from adding a document to my index which is already there (or at
least partially there). However, more like this only works on documents
which are *already* in the index. Ideally what I would be able to do is:
post an xml document to solr, and receive a MLT response (the same kind of
MLT response I would recieve had the document been in Solr already, and
queried with id=#{id}&mlt=true).
Is anybody aware of how I could achieve this functionality leveraging
existing handlers? If not I will bump over to solr-dev and see if this is a
tractable problem.
Thanks in advance,
