Thanks, this looks good. mm and fq don't seem to be working for a nested query, but I should be able to work around it. I was unable to find much documentation on the Wiki, API docs or in the Solr book - please let me know if you are aware of any other documentation for this feature apart from the mentioned blog post.

Note not fully URL-encoded for clarity: &defType=lucene&q= _query_:"{!edismax qf='p,q,r' fq='field1:xyz'}abc def" AND _query_:"{!edismax mm=100% qf='q, r, s'}jlk" On 5/17/2011 2:55 AM, Nikhil Chhaochharia wrote: > Hi, > > I am using Solr 3.1 with edismax.
