• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - thanh trung cua nhu ((phuong mai) OR (phuong tay)) toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu sang)) - thanh trung cua nhu ((phuong mai) OR (phuong tay)) toan ban~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chieu sang)) - thanh trung cua nhu ((phuong mai) OR (phuong tay)) toan ban*.
