What are qf_dismax and pf_dismax? They are meaningless to
Solr. Try adding &debugQuery=on to your URL and you'll
see the parsed query, which helps a lot here....

If you change these to the proper dismax values (qf and pf)
you'll get beter results. As it is, I think you'll see output like:

<str name="parsedquery">+() ()</str>

showing that your query isn't actually going against
any fields....
