problems with boolean query

Hi all!

I have a question regarding boolean queries. What I want to reach:

Return all documents where string-field „access" has value ‚allow*‘ or is not set.

My query:
fq = (access:Allow*) OR (-access:*)

But I got only the results where the field has value ‚allow*‘.

I am using solr 4.3.1 with the edismax query parser.

I am looking forward to get some hints, why the query might be failing.

Best regards and many thanks!
Thomas

Yeah, purely negative sub-queries have had problems, so rewrite:

fq = (access:Allow*) OR (-access:*)

as

fq = (access:Allow*) OR (*:* -access:*)
