• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky tang ma hoa. ((hieu ve) OR (hieu van)) cam ((tuc van) OR (thuc vat)) anh voi hoa viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky tang ma hoa. ((hieu ve) OR (hieu van)) cam ((tuc van) or (thuc vat)) anh voi hoa viet*".
