• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y sang tao hai. hieu ve ((cac xuc) OR (cam xuc)) ((van hanh) or (va thanh)) vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y sang tao hai. hieu ve ((cac xuc) OR (cam xuc)) ((van hanh) OR (va thanh)) vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y sang tao hai. hieu ve ((cac xuc) OR (cam xuc)) ((van hanh) or (va thanh)) vi cua triet".
• Adding a wildcard symbol may retrieve word variants: tu sach y sang tao hai. hieu ve ((cac xuc) OR (cam xuc)) ((van hanh) or (va thanh)) vi cua triet*.
