• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky ((nang xa) OR (nang ma)) hoi. ((hieu hien) OR (hieu ve)) cap nuoc va hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky ((nang xa) OR (nang ma)) hoi. ((hieu hien) or (hieu ve)) cap nuoc va hanh vai cua te*".
