• If you are trying to use Boolean operators, they must be ALL CAPS: doc ((hieu manh) OR (hieu nganh)) - thanh trang va thuong cong ((manh tuan) OR (anh xuan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc ((hieu manh) OR (hieu nganh)) - thanh trang va thuong cong ((manh tuan) or (anh xuan)) cao".
• Adding a wildcard symbol may retrieve word variants: doc ((hieu manh) OR (hieu nganh)) - thanh trang va thuong cong ((manh tuan) or (anh xuan)) cao*.
