• Performing a fuzzy search may retrieve terms with similar spellings: ((su cac) OR (tu cac)) ky ((nang xa) or (tang ma)) hoi. hieu ve cam duc ban hanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cac) OR (tu cac)) ky ((nang xa) OR (tang ma)) hoi. hieu ve cam duc ban hanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) OR (tu cac)) ky ((nang xa) or (tang ma)) hoi. hieu ve cam duc ban hanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: ((su cac) OR (tu cac)) ky ((nang xa) or (tang ma)) hoi. hieu ve cam duc ban hanh dai cua te*.
