• If you are trying to use Boolean operators, they must be ALL CAPS: tu cao ky nang ((((mai hoi) OR (lai hoi))) OR (mai khoi)). hieu ve cham tuc ban thanh vi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cao ky nang ((((mai hoi) OR (lai hoi))) or (mai khoi)). hieu ve cham tuc ban thanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cao ky nang ((((mai hoi) OR (lai hoi))) or (mai khoi)). hieu ve cham tuc ban thanh vi cua tre*.
