• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (tien manh)) - thanh ((cong cua) OR (cong cu)) thong cong san than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) or (tien manh)) - thanh ((cong cua) OR (cong cu)) thong cong san than cau".
