• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky ((lang xa) or (((dang van) OR (hoang van)))) hoi. hieu ve cham duc van hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((lang xa) OR (((dang van) OR (hoang van)))) hoi. hieu ve cham duc van hanh vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((lang xa) or (((dang van) OR (hoang van)))) hoi. hieu ve cham duc van hanh vai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sai ky ((lang xa) or (((dang van) OR (hoang van)))) hoi. hieu ve cham duc van hanh vai cua tre*.
