• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ke mang lai hoi. ((hieu du) OR (hieu su)) 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 ke mang lai hoi. ((hieu du) OR (hieu su)) chat ((xuc va) or (loc va)) hanh vi cua te*".
