boosting MoreLikeThis results

[Bill Au]

I have a need to boost MoreLikeThis results.  So far the only boost that I
have come across is boosting query field by using mlt.qf.  But what I really
need is to use boost query and boost function like those in the
DisMaxRequestHandler.  Is that possible at all either out-of-the-box or by
writing a custom handler, or are we limited by the MoreLikeThis of Lucene?

Lucene's MLT just builds a query, augmenting that query with additional
boost/function queries should be straight forward.

As i mentioned in another thread: we should really refactor
MoreLikeThisHandler into a MoreLIkeThisQParserPlugin ... that way you
could mix and match it with other boosts using the "query" function type.
