Hi all, I''d like to write my own TokenStream Filter (in lucene this would be a subclass of a TokenFilter, which ferret seems to lack) but I''m not sure how to go about it. Specifically, it''s not clear how I''d create a non-trivial TokenStream to pass out to any filters that wrapped mine. Can anyone point me towards a code example? Thanks. -- Richard Jones
