 Weel, I cannot change the index, it already has his name... it is a 
collection of thousands of object, this one I want to pre-filter before 
index are just a small part...

 Or you mean I have to do something about  SearchableText()?

 I have to index in a way the user find the term even if it does not use 
accented letters on a current index that already has indexed thousands 
of objects...

 Can I hook somewhere in the middle, so I Index them in the way I want? :)
