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