using dismax
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

Did i write wt? Oh dear. The q and w are too close =)

Markus,
Its not wt its qt, wt for response type,
Also qt is not for Query Parser its for Request Handler ,In solrconfig.xml
there are many Request Handlers can be Defined using "dismax" Query Parser
Or Using "lucene" Query Parser.
If you want to change Query parser then its "defType" parameter for
defining Query Parser .
And you are right if defType=dismax ,then there must be "qf" parameter to be
given.

Thanx:
Grijesh

Erick,
The wt parameter does not specifiy the parser but the request handler to use.
Except the confusion between parser and request handler you're entirely right.
Cheers

If you're trying to get to a dismax parser (named "dismax" in
solrconfig.xml),
you need to specify qt=dismax. NOTE: the Wiki is a bit confusing on this
point, the fact that the dismax parser is *named* dismax in the
solrconfig.xml
file is coincidence, you could name it "erick" and specify qt=erick and get
there.
Markus' comments are if you're specifying a dismax parser entirely on the
request
line, not getting to the one you may have defined in solrconfig.xml. Both
are entirely
valid ways of using dismax....
Best
Erick

Re: using dismax

with dismax you must specifiy fields to query upon in the qf parameter and the
value for which you want to search through those fields in q.
defType=lucene&q=poi_id:3
defType=dismax&q=3&qf=poi_id
See the DisMaxQParser wiki for more
