• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky sang tai hai. hieu ve cam xuc ((va dinh) OR (va dan)) ((vi cua) OR (di cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky sang tai hai. hieu ve cam xuc ((va dinh) or (va dan)) ((vi cua) OR (di cua)) te*".
