• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (thien thanh)) - hanh ((trang tuan) OR (trung tuan)) dang cong dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thien anh) or (thien thanh)) - hanh ((trang tuan) OR (trung tuan)) dang cong dan than cap".
