I agree with Erick, but if you want the special characters to count in searches, you might consider not just stripping them out but replacing them with textual placeholders (which would also have to be done at indexing time). For instance, I replace C# with csharp and C++ with cplusplus during indexing and during searching before passing them along to my solr layer.

You'll need it. Problem is this is such a sticky wicket. You can move the cleaning up to the PHP layer, that is strip out the parens. You could write a Solr component that got the query _very_ early and transformed it. You'd have to get here before parsing. Either way, though, you'll be endlessly trying to second-guess the query parsing and/or intent of the user. I'd recommend the PHP layer if anything, it's closer to the user and you may have a better chance to guess right.
