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