using dismax

[Tri Nguyen]

Hi,
 
Maybe I'm missing something obvious.
 
I'm trying to use the dismax parser and it doesn't seem like I'm using it 
properly.
 
When I do this:
http://localhost:8080/solr/cs/select?q=(poi_id:3)
 
I get a row returned.
 
When I incorporate dismax and say mm=1, no results get returned.
http://localhost:8080/solr/cs/select?q=(poi_id:3)&defType=dismax&mm=1
 
What I wanted to do when I specify mm=1 is to say at least 1 query parameter 
matches.
 
What am I missing?
 
Thanks,
 
Tri
