• Performing a fuzzy search may retrieve terms with similar spellings: ((tu can) OR (tu cac)) ky lang van hoi. hieu tu nhan luc ((va hanh) or (dia danh)) dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu can) OR (tu cac)) ky lang van hoi. hieu tu nhan luc ((va hanh) OR (dia danh)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu can) OR (tu cac)) ky lang van hoi. hieu tu nhan luc ((va hanh) or (dia danh)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu can) OR (tu cac)) ky lang van hoi. hieu tu nhan luc ((va hanh) or (dia danh)) dai cua tre*.
