I posted a while back with this problem and I've finally got it working
using the following method:
in solrconfig.xml:
<requestHandler name="mlt" class="solr.MoreLikeThisHandler">
<lst name="defaults">
<str name="mlt.fl">id,title</str>
<int name="mlt.mintf">0</int>
</lst>
</requestHandler>
then when making the request, I do a normal search for the item with the
necessary filter query (in my case discontinued:false) and set the
qt=mlt to activate the mlt handler.
So in your case:
http://localhost:8983/solr/select?q=id:SP2514N&mlt.fl=manu,cat&mlt.mindf=1&mlt.mintf=1&fq=popularity:6&mlt.displayTerms=details&mlt=true&qt=mlt
I had to use qt because I'm using a library to access solr and it
doesn't include support for alternative handlers at the path level.

Sorry. The examples on the wiki aren't working with the 'fq' to
filter the similarities. It just filters the actual queries.

The popularity of the doc found is 6, and trying to use
'fq=popularity:6' brings back similarities with a popularity other
than 6.

Hm. I checked out a clean Solr 1.3.0 and indexed the example docs
and set up a simple MLT handler the example queries on the Wiki work
fine (fq can filter out docs). Our build has a slight change to
QueryComponent so another query isn't done when we use
localsolr+field collapsing, but that change doesn't look like it
would make a difference. It just conditionally sets
rb.setNeedDocSet() to true or false.
Will run some tests on a clean fresh build of Solr to see if it's our
build.

Doug,
does the good old 'fq' not work with MLT? It should...

Subject: MoreLikeThis filtering
Is it possible to filter similarities found by the MLT
component/handler?
Something like mlt.fq=site_id:86?
We have 32 cores in our Solr install, and some of those cores have
up to 8 sites
indexed in them. Typically those cores will have one very large
site with a few
hundred thousand indexed documents, and lots of small sites with
significantly
less documents indexed.
We're looking to implement a MLT component for our sites but want
the similar
stories to be only for a specific site (not all sites in the core).
Is there a way to do something like this, or will we have to make
mods (I'm not
seeing anything jump out at me in the Solr 1.3.0 or Lucene 2.4.0
code)?
/solr/dsteiger/mlt?q=story_id:188665+AND+site_id:86&mlt.fq=site_id:86
(We have all all of our other defaults set up in the handler config.)
Thanks.
