query(subquery, default) filters results

[Matteo Grolla]

Hi everybody,
        I'm having troubles with the function query

"query(subquery, default)"                      
http://wiki.apache.org/solr/FunctionQuery#query

running this 

http://localhost:8983/solr/select?q=query($qq,1)&qq={!dismax qf=text}hard drive

on collection1 gives me no results
but I was expecting the query to match all documents and obtain score=1 where
hard drive
didn't match


Can you tell me where I'm wrong?

tried on Solr 4.2.1 and solr 4.5.0
