In the original design of ZCTextIndex we (PythonLabs mostly) considered stemming and found that it has been found to have dubious value in many information theorists views (The fact that Google does no stemming was also a factor in the decision). So we decided to leave it out entirely.
ZCTextIndex is extensible and third parties can add additional text processing facilites (called pipeline elements) to the system without modifying ZCTextIndex. This could be a way to add stemming and any other conceivable feature involving preprocessing the index source and query text. Granted that feature could use better(!) documentation... (I should just add that to my email sig ;^) -Casey On Friday 08 November 2002 08:19 am, Jens Vagelpohl wrote: > > Depends on your needs.
