• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh trung cua nang luong dan ((than cau) OR (((than cap) OR (thanh lap))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung cua nang luong dan ((than cau) or (((than cap) OR (thanh lap))))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung cua nang luong dan ((than cau) or (((than cap) OR (thanh lap))))*.
