[EP-tech] OAI : need some explanations about custom sets and filters

Hi there

As we do need to define an OAI custom set into our repository, I'd like to know 
if the different filters criteria work only with an implicit "AND" operator 
(unfortunately not "OR"), and if exists a negative operator (kind of "!=>")...

Regards
