• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly ((hang ca) OR (hang tai)) hoi. lieu va cam thu vat ((danh vai) OR (danh sai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly ((hang ca) OR (hang tai)) hoi. lieu va cam thu vat ((danh vai) or (danh sai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ly ((hang ca) OR (hang tai)) hoi. lieu va cam thu vat ((danh vai) or (danh sai)) cua tre*.
