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