• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ty ((nang ma) OR (lang van)) hoi. hieu va cham tuc dia danh le cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) OR (thu sach)) ty ((nang ma) or (lang van)) hoi. hieu va cham tuc dia danh le cua te~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) OR (thu sach)) ty ((nang ma) or (lang van)) hoi. hieu va cham tuc dia danh le cua te*.
