accessing the query string from inside TokenFilter

Dear list,
while writing some TokenFilter for my analyzer chain I need access to
the query string from inside of my TokenFilter for some comparison, but the
Filters are working with a TokenStream and get seperate Tokens.
Currently I couldn't get any access to the query string.

Any idea how to get this done?

Is there an Attribute for "query" or "qstr"?

Regards Bernd

I don't think there is anything like that but this could be useful. We
could add this and make it optional on the query parser? Maybe even in
lucene. can you bring this to the dev list?
