Let’s see the results of adding &debug=query to the query, in particular the parsed version.
Because what you’re reporting doesn’t really make sense. edismax should be totally ignoring the “qf” parameter since you’re specifically qualifying all the clauses with a field. Unless you’re not really enclosing the search text in parentheses (or quotes if they should be phrases). Also, if you’re willing to form separate clauses like this, there's no reason to even use edismax since its purpose is to automatically distribute search terms over multiple fields and you’re explicitly specifying the fields..
