Oleg,
The Porter stemming stems herring and herrings to her, which is a bit unfortunate. A quick fix is to put 'herring/herrings' in the exception list in the english (porter2) stemmer, but I'll look at this case over the next few days and see if I can come up with something a bit better. Interesting that no one has reported this before. Martin ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
