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 fear nobody of us knows this. Therefore, you must yourself look at the sources. If you need this feature and "ZCTextIndex" does not provide it, then you may use a different text index. I know that with "TextIndexNG3" you can select different parsers (among others a parser that does not interpret '(' and ')') or provide your own one.

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.

Then, you will need to change the lexicon as well. Usually, the lexicon breaks words at non alnum characters (with a few exeptions). Again, when I remember right, "TextIndexNG3" allows you to specify additional "word characters" (which do not lead to word braking). -- Dieter

I said Yes :)

Enclosing the words with double quotes has not helped, neither have backslashes...

You have to enclose your string with double quotes and then with single quote. So the parser gets the double quotes with the search string The parser does not interpret the string between double quotes. It works for me :) suppose you are searching for: my text (really good text) to search for txt = '"my text (really good text) to search for"' brains = context.portal_catalog(searchableText=text) HTH

Is there a way other than having to write a new ZCTextIndex?

Thanks for any insight

Robert
