• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky long ha noi. hieu van cam ((xuc va) OR (duc va)) anh va ((chi tri) OR (cai tri)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky long ha noi. hieu van cam ((xuc va) or (duc va)) anh va ((chi tri) OR (cai tri))".
• Adding a wildcard symbol may retrieve word variants: tu sach ky long ha noi. hieu van cam ((xuc va) or (duc va)) anh va ((chi tri) OR (cai tri))*.
