Subject Re: Snowball and protected words

Hello Walter.

We believe this kind of thing is better managed by a content team that 
works with user feedback. It would be costly everytime we find a word 
that brings irrelevant results the fact that, to correct that, we'd need 
to build a new stemmer. It's a lot better to create a simple interface 
that allows anyone to define which are the protected words we need 
according to user feedback in a simple, easy way.

Erik just said it wouldn't be hard to bring that functionality to 
Snowball. Erik, do you know what needs to be done in order to achieve 
that? Don't you guys have plans for that? I'm sure that I'm not the only 
one with that problem using SOLR with portuguese language (or any other 

Thank you very much for your help,
