• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky lang hoa hoi. hieu le nam thuc van hanh vai ((cua triet) or (((cua viet) OR (ca viet))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang hoa hoi. hieu le nam thuc van hanh vai ((cua triet) OR (((cua viet) OR (ca viet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang hoa hoi. hieu le nam thuc van hanh vai ((cua triet) or (((cua viet) OR (ca viet))))".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang hoa hoi. hieu le nam thuc van hanh vai ((cua triet) or (((cua viet) OR (ca viet))))*.
