• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ky mang) OR (ky dang)) lai hoi. hieu du chat ((xuc va) OR (loc va)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ky mang) OR (ky dang)) lai hoi. hieu du chat ((xuc va) or (loc va)) hanh vi cua te*".
