Range query and join, oarse exception when parens are added

[Mark Olsen]

Solr version 4.2.1

I'm having an issue using a "join" query with a range query, but only when the 
query is wrapped in parens.

This query works:

{!join from=member_profile_doc_id to=id}language_proficiency_id_number:[30 TO 
50]

However this query does not (just wrapping with parens):

({!join from=member_profile_doc_id to=id}language_proficiency_id_number:[30 TO 
50])

Caused by: org.apache.solr.parser.ParseException: Encountered "<EOF>" at line 
1, column 34.
Was expecting one of:
    "TO" ...
    <RANGE_QUOTED> ...
    <RANGE_GOOP> ...

Is this a known bug in this version of Solr (4.2.1)?

Thank you,
