When I try to search the forums, I frequently get the message:
Cannot invoke the operation : the module threw an exception
For example, I get this message if my search string is "foo AND bar" and I select the "Search for any terms or use query as entered" radio button.
Am I doing something wrong or is searching broken?
Post an example as a bug on sourceforge.
If you are doing it wrong, it should give you a better error message.
