• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach ky) OR (sach ty)) nang ((ma hoi) or (ma hoa)). hieu van cam xuc van hanh tri cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach ty)) nang ((ma hoi) OR (ma hoa)). hieu van cam xuc van hanh tri cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sach ty)) nang ((ma hoi) or (ma hoa)). hieu van cam xuc van hanh tri cua te".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) OR (sach ty)) nang ((ma hoi) or (ma hoa)). hieu van cam xuc van hanh tri cua te*.
