• If you are trying to use Boolean operators, they must be ALL CAPS: lang rom ein ((drive change) OR (price change)) using long ((dong sind) OR (dong sein)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang rom ein ((drive change) OR (price change)) using long ((dong sind) or (dong sein)) ;*".
