Subject Re: Dismax request handler differences Between Solr Version 3.5 and 1.4
Date Thu, 12 Apr 2012 23:47:35 GMT
Then I suspect your solrconfig is different or you're using a *slightly*
different URL. When you specify defType=dismax, you're NOT going
to the "dismax"  requestHandler. You're specifying a "dismax" style
parser, and Solr expects that you're going to provide all the parameters
on the URL. To whit: qf. If you add "&qf=field1 field2 field3..." you'll
see output.

I found this extremely confusing when I started using Solr. If you use
&qt=dismax, _then_ you're specifying that you should use the
requestHandler defined in your solrconfig.xml _named_ "dismax".

And this kind of thing was changed because it was so confusing, but
I suspect your 3.5 installation is not quite the same URL. I think 3.5
was changed to use the default field in this case.

BTW, 3.6 has just been released, if you're upgrading anyway you
might want to jump to 3.6

Best
