jira problem: grouping search terms not working.

I wanted to search in jira for (X OR Y) AND NOT Z

JIRA supports using parentheses to group clauses to form sub queries. This can be very useful if you want to control the boolean logic for a query.

To search for either "atlassian" or "jira" and "bugs" use the query:

(atlassian OR jira) AND bugs

Am I doing something wrong?

I don't think so, this looks like a JIRA (or rather Lucene) issue to me. Using
"bugs AND (atlassian OR jira)" works for me, it seems something doesn't like a
query to start with a parentheses.

BTW: +(atlassian jira) +bugs does the same and is much easier to type ;)
