• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - hanh tang cua thong cong tac ((toan tap) OR (((toan ban) OR (van ban))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh tang cua thong cong tac ((toan tap) or (((toan ban) OR (van ban))))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh tang cua thong cong tac ((toan tap) or (((toan ban) OR (van ban))))*.
