No, the MLT feature does not have that kind of field-specific
boosting capability. It sounds like it could be a useful enhancement
though. Of course you do get boosts for "interesting terms" already,
but maybe having an additional field-specific boost would be a nice
touch too.

I know that only one query of that type does not change anything.
But when it's two or more with different boosts, i hope it does.
Here is the situation:
My docs have "Title" and "Description". What I want to do is to
give more relevancy to the morelikethis on the title than on the
description. So the query would be like this:
query = (words^0.4 in^0.3 the^0.56 title^0.65)^0.70 (words^0.7
in^0.33 the^0.49 description^0.43)^0.30
This way, the words in the title are more relevant than the words
in the description, right?
Thanks!

Is it possible to boost the query that MoreLikeThis returns
before sending it to Solr? I mean, technically is possible,
because you can add a factor to the whole query but...does it
make sense? (Remember that MoreLikeThis can already boosts each
term inside the query).
For example, this could be a result of MoreLikeThis (with native
boosting enabled)
queryResultMLT = (this^0.4 is^0.5 a^0.6 query^0.33 of^0.29
morelikethis^0.67)
what I want to do is
queryResulltMLT = (this^0.4 is^0.5 a^0.6 query^0.33 of^0.29
morelikethis^0.67)^0.60 <---(notice the boost of 0.60 for
the whole query)
That last boost wouldn't change the doc ordering at all, so it'd
be kinda useless.
What are you trying to accomplish?
