• If you are trying to use Boolean operators, they must be ALL CAPS: so ((sang ky) OR (((sang kyo) OR (sang cho)))) lang ha hoi. hieu van hac xuc cac dan di cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so ((sang ky) or (((sang kyo) OR (sang cho)))) lang ha hoi. hieu van hac xuc cac dan di cua te".
• Adding a wildcard symbol may retrieve word variants: so ((sang ky) or (((sang kyo) OR (sang cho)))) lang ha hoi. hieu van hac xuc cac dan di cua te*.
