• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((nang xa) or (nang ma)) hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh dai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (nang ma)) hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh dai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) or (nang ma)) hoi. hieu va ((cam cuc) OR (pham cuc)) ban thanh dai cua te*".
