• Performing a fuzzy search may retrieve terms with similar spellings: vu bach y sang ma hoi. lieu ((va tham) OR (van tham)) hoc ((va dan) or (va hanh)) vai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu bach y sang ma hoi. lieu ((va tham) OR (van tham)) hoc ((va dan) OR (va hanh)) vai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu bach y sang ma hoi. lieu ((va tham) OR (van tham)) hoc ((va dan) or (va hanh)) vai cua triet".
• Adding a wildcard symbol may retrieve word variants: vu bach y sang ma hoi. lieu ((va tham) OR (van tham)) hoc ((va dan) or (va hanh)) vai cua triet*.
