No, not really. You'll have to do that as a copyField if providing a wildcard is important to you, in effect copying everything into a single field and then querying that field.
You can supply multiple fields through qf without specifying each field in the q parameter as long as you're using the edismax query handler - that's usually more flexible, but it will still require each field to be specified.
There's also a little known feature named "Field aliasing using per-field qf overrides" (I'm wasn't aware with it, at least). If I've parsed what I've been able to find from a few web searches correctly, you should be able to do f.i_fields.qf=internal internet interface&qf=i_fields. In effect creating an i_fields alias that refers to those three fields. You'll still have to give them explicitly.
