Hello, I have been playing off and on with the more like this patch and I
really want to get it working well. I have the patch installed and I have
about 500K bibliographic records in my solr index.
My MLT query uses a fieldlist of about 5 or 6 fields. There are a mix of
string and text fields. They are all in a TermVector. I have played around
with the mindf values. With about 90% of my mlt queries solr it returns no
matches and the remaining 10% get completely irrelevant results.
Are there any "best practices" for the MLT search or am I possibly doing
something wrong?
Thanks

If you are using MLT on the standard request handler, try debugging with
the MoreLikeThisRequestHandler (/mlt).
as brian suggests, set debugQuery to true and make sure the generated
query looks ok.
also add "&mlt.displayTerms=details" to see what terms are getting used.
I'm not exactly sure what query gets constructed from 6 fields - you may
find some wierdness if different tokenizers/analyzers. Perhaps try MLT
with 1 or two fields and see if the results make sense, them add more
fields...
