: is it possible to use MLT as a nested query? I tried the following:
: ....select?q=field1:foo field2:bar AND _query_:"{!mlt fl=mltField mindf=1
mintf=1 mlt.match.include=false} selectField:baz}"
MLT functionality exists in two forms: as a component, that decorates
results produced by another search (similar to highlighting and faceting),
and as a handler that produces a main result set based on an MLT query (so
highlighting and faceting happen to the results of the MLT itself)...

In order for what you are describing to work, someone would have to
implement a MLT "QParser" but no one has ever attempted that to my
knowledge. I have considered looking into it, and i suspect it would be
somewhat straight forward to do, but only for single node instances --
there is no way i know of for a QParser to sanely generate a query like
MLT based on the terms of distributed shards.
