• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (theo chu)) sang - thanh thang va thuong cong van ((tan ban) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) OR (theo chu)) sang - thanh thang va thuong cong van ((tan ban) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) OR (theo chu)) sang - thanh thang va thuong cong van ((tan ban) or (toan ban))*.
