• Performing a fuzzy search may retrieve terms with similar spellings: ((so sach) or (bo sach)) thu lang mai hoi. hieu v pham huu ((va thanh) OR (va tinh)) van cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (bo sach)) thu lang mai hoi. hieu v pham huu ((va thanh) OR (va tinh)) van cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (bo sach)) thu lang mai hoi. hieu v pham huu ((va thanh) OR (va tinh)) van cua te".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (bo sach)) thu lang mai hoi. hieu v pham huu ((va thanh) OR (va tinh)) van cua te*.
