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