Perhaps you should try some spelling variations:
reforms drivers » platforms drivers
reforms crises » reforms cases, reforms across, reforms case
transfer lim » transfer beim, transfer law, transfer axiom
lim mark » im markt, im marz
luis rdf » luis de
rdf data » dlf data, imf data

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis f _ transfer lim mark ) OR ( luis rdf data ((reforms crises) OR (reforms drivers)) case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis f _ transfer lim mark ) or ( luis rdf data ((reforms crises) OR (reforms drivers)) case ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis f _ transfer lim mark ) or ( luis rdf data ((reforms crises) OR (reforms drivers)) case ))*.
