• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien tinh) OR (thien tinh)) - thanh trung va nhung tuong dan ((thai cao) OR (tho cac)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien tinh) OR (thien tinh)) - thanh trung va nhung tuong dan ((thai cao) or (tho cac))".
