• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ((xang xa) OR (lang xa)) hoi. hieu van cam duc va dinh lai ((chay tren) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((xang xa) OR (lang xa)) hoi. hieu van cam duc va dinh lai ((chay tren) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((xang xa) OR (lang xa)) hoi. hieu van cam duc va dinh lai ((chay tren) or (cau tren))*".
