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