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