• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ly lang xa hoi. hieu ((va tham) or (ve chat)) luc van toan vang ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly lang xa hoi. hieu ((va tham) OR (ve chat)) luc van toan vang ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly lang xa hoi. hieu ((va tham) or (ve chat)) luc van toan vang ((cua tre) OR (cua te))*".
