MoreLikeThis is interesting. So in order to use it through the
MoreLikeThisHandler, I should use the unique field in
the "q" param to uniquely identify the "this" document? Or, does
it also support a more common query and works as "More Like These"
just like using this feature through the StandardRequestHandler?
Jack - I think all of your questions are answered on the wiki page
with the examples. The "q" parameter is a full Solr query parser
expression, so you can pick one or more documents with it.

I have some documents, each has a number of tags. I'd like to
have a query to return "similar" documents which share largest
number of tags with a given document. For example, if I have
doc that has 4 tags, and I'd like to return docs that also
have these 4 tags. And if this doesn't make up a number of records,
say, 10 records, I'd like to have some more docs that share 3
of the tags. And if this is still not enough, those sharing 2
tags... I wonder if there is a way to construct a solr query
to do this?
The MoreLikeThis handler may get you close enough to what you're
after:
<http://wiki.apache.org/solr/MoreLikeThis>
It's in the trunk codebase, so try out a recent nightly build.
