• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu san) OR (tu ban)) ky nang xa hoi. hieu ve cam tuc va trinh ((vi cua) OR (vai cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu san) or (tu ban)) ky nang xa hoi. hieu ve cam tuc va trinh ((vi cua) OR (vai cua)) te".
