• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((((y nang) OR (ky nang))) or (v nang)) ma hoa. hieu va co duc va thanh dai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((((y nang) OR (ky nang))) OR (v nang)) ma hoa. hieu va co duc va thanh dai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((((y nang) OR (ky nang))) or (v nang)) ma hoa. hieu va co duc va thanh dai cuu tre".
• Adding a wildcard symbol may retrieve word variants: te sach ((((y nang) OR (ky nang))) or (v nang)) ma hoa. hieu va co duc va thanh dai cuu tre*.
