[Zope-dev] Escaping special characters in ZCTextIndex.QueryParser?

Hi, is it possible to escape parentheses in ZCTextIndex searches? If not, why not and how can I do a simple search in an index bypassing the QueryParser? I have an index where words can contain parentheses and I am unable to enter a query for these words because the QueryParser interprets all parentheses as search expression groupings. Enclosing the words with double quotes has not helped, neither have backslashes... Is there a way other than having to write a new ZCTextIndex? Thanks for any insight Robert
