• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((san ky) OR (van ky)) sang lap hoi. hieu ((vu cham) OR (va cham)) duc van thanh dai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((san ky) or (van ky)) sang lap hoi. hieu ((vu cham) OR (va cham)) duc van thanh dai cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((san ky) or (van ky)) sang lap hoi. hieu ((vu cham) OR (va cham)) duc van thanh dai cua te*.
