• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) OR (thuoc sach)) ky van cay phoi. lieu va cam loc va hanh vi ((cau treo) or (cua tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (thuoc sach)) ky van cay phoi. lieu va cam loc va hanh vi ((cau treo) OR (cua tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) OR (thuoc sach)) ky van cay phoi. lieu va cam loc va hanh vi ((cau treo) or (cua tre))*".
