• Performing a fuzzy search may retrieve terms with similar spellings: su cac tri nang x ho. hieu ((va cam) OR (va cao)) xuc ((va hanh) or (ban hanh)) hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su cac tri nang x ho. hieu ((va cam) OR (va cao)) xuc ((va hanh) OR (ban hanh)) hai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su cac tri nang x ho. hieu ((va cam) OR (va cao)) xuc ((va hanh) or (ban hanh)) hai cua triet".
• Adding a wildcard symbol may retrieve word variants: su cac tri nang x ho. hieu ((va cam) OR (va cao)) xuc ((va hanh) or (ban hanh)) hai cua triet*.
