Hi Ryan,
My approach to this problem looked at modifying the
MoreLikeThisHelper.getMoreLikeThis() methods in
MoreLikeThisHandler.javasource file.
By taking the Query object returned by "mltquery = mlt.like(id);" (line 257)
and "mltquery = mlt.like(reader);" (line 274) and adding additional
BooleanClauses to it before the respective calls to searcher.getDocList()
(lines 269 & 278), I was hoping to modify the query used to generate the
list of related documents ("response") rather than the MoreLikeThis query
itself ("match").
It seemed fairly straightforward at first since the modifications did not
require any changes to the Lucene MoreLikeThis system, however
I ran into some problems because the MoreLikeThisHelper class doesn't have
access to the SolrQueryRequest req object from the MoreLikeThisHandler
class, and since my knowledge of Solr internals is limited I was hoping
someone with a bit more experience would be able to provide some guidance.
thanks,
Tristan

If you need to modify the query, this is the place to look.
