• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((sang lai) OR (sang lap)) hoi. hieu su chat xuc ((va hanh) OR (van hanh)) vai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((sang lai) OR (sang lap)) hoi. hieu su chat xuc ((va hanh) or (van hanh)) vai cua te".
