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).

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

2007-11-25 Thread Robert Casties
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
