• If you are trying to use Boolean operators, they must be ALL CAPS: a ((cua tinh) OR (ha tinh)) - thanh ((trung cua) OR (trung cap)) hang cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "a ((cua tinh) OR (ha tinh)) - thanh ((trung cua) or (trung cap)) hang cong dan toan cao".
