• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach ty)) lang xa hoi. hieu qua cam xuc va hanh ((vi cua) OR (vai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach ty)) lang xa hoi. hieu qua cam xuc va hanh ((vi cua) or (vai cua)) triet".
