• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky ((nang xa) OR (nang x)) hoi. hieu van cac toc xa danh ((vai cua) OR (hoi cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky ((nang xa) OR (nang x)) hoi. hieu van cac toc xa danh ((vai cua) or (hoi cua)) tre".
