• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty tang van hoi. hieu ((van cam) OR (van lam)) xuc ((va dan) or (ca dan)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty tang van hoi. hieu ((van cam) OR (van lam)) xuc ((va dan) OR (ca dan)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty tang van hoi. hieu ((van cam) OR (van lam)) xuc ((va dan) or (ca dan)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach ty tang van hoi. hieu ((van cam) OR (van lam)) xuc ((va dan) or (ca dan)) vi cua triet*.
