• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((thanh truong) OR (thanh tung)) quan nhung cong ((ban than) OR (van thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((thanh truong) OR (thanh tung)) quan nhung cong ((ban than) or (van thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((thanh truong) OR (thanh tung)) quan nhung cong ((ban than) or (van thanh)) cau*.
