Right, so I have a field with many terms in it and I want to find similar
documents using this against a number of other fields. In my situation, I
want to take the description field and look in description, city, and
province. I want the city and province fields to be "more important". I have
applied a boost to them, but even though they have higher values they are
not considered by Solr to be as "interesting", I think because they do not
occur as frequently. What ends up happening is that all of the matching
terms in the description field end up pushing the matching terms from city
and province to the bottom of the "interesting" list.

I think that's what you were saying in the second paragraph, right? There
currently doesn't seem to be a way to influence the ordering of the
interesting terms.

Thanks,
Nick

In the current code base the MLT Handler has geneerally been superceeded 
by a MLT Component which may do what you want -- you can use an QParser 
you want to generate a DocList and the MLT Component then suggests similar 
docs for each doc in your list.

As i said: that may be what you're looking for (it's hard to tell based on 
your email) but the other possibility is that you want to be able to 
specify bq (and maybe bf) type parrams to influence the MLT portion of the 
request (ie: apply a bias so docs matching a particular query/func are 
mosre likely to be suggested) ... this is an area that hasn't really been 
very well explored as far as i can remember.
