Is there a Solr query parser that will parse out and create filter queries?

Question

I'm looking for a Solr query parser that can parse out and correctly apply filter queries, leaving anything not specified with a field as a general search term.

So:

tags:sql title:mysql recordset

This would do the following:

• Create a FilterQuery query for records with "sql" in the "tags" field
• Create a FilterQuery for records with "mysql" in the "title" field
• Create a normal query for records with "recordset" in the default field

Does such a query parser exist?

Edit: I've found that if I search for "*" as the query, and then do the "qf" param as this, it works:

tags:sql AND title:mysql AND recordset

What are the drawbacks to doing this? I assume scoring would be all wrong?
