• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu khang) OR (trien quang)) - thanh trung cap thong huong ((dan toan) OR (van toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu khang) or (trien quang)) - thanh trung cap thong huong ((dan toan) OR (van toan)) cau*".
