• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - thanh ((trung tam) OR (trang va)) nhung cong tac than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu tinh)) - thanh ((trung tam) or (trang va)) nhung cong tac than cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu tinh)) - thanh ((trung tam) or (trang va)) nhung cong tac than cap*.
