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

Hi

If EPrints::DataSet::prepare_search calls EPrints::Search::new, I don't see 
exactly how one could "define a key on the oai set config to switch satisfy_all 
between 1 and 0 as necessary" in such an overloading version of oai2 script...

Best regards
Laurent Cloarec
