Solr dismax query returns no data, while standard query does

I am unable to find any result when calling query like that:

http://localhost:8983/solr/somecore/select?q=title:king&wt=json&defType=dismax

But calling query like this:

http://localhost:8983/solr/somecore/select?q=title:king&wt=json

Finds as expected 9 documents.

I tried various things (like for example qildcard: :, to no avail).

If anyone could point me to problem or documentation that may explain me what I am doing wrong.

If it's matters, schema.xml is as follows:

Got solution, for some unknown to me reason, q=king is not going work unless we define which field should be used for filtering, in my case:

http://localhost:8983/solr/somecore/select?q=king&wt=json&defType=dismax&qf=title+body

PS

Of course "title:" should be omitted as well. I did not mention it in original question, but I tried with and without it in query.
