• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (tu sach)) o lang xa hoi. thien van chat doc ban benh vi ((cuu tre) or (cau tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) o lang xa hoi. thien van chat doc ban benh vi ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (tu sach)) o lang xa hoi. thien van chat doc ban benh vi ((cuu tre) or (cau tren))*".
