• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky nang lai hoa. hieu ve cam ((xuc va) OR (duc va)) hanh ((vi cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky nang lai hoa. hieu ve cam ((xuc va) or (duc va)) hanh ((vi cua) OR (vai cua)) triet".
