• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sach)) - canh manh cua nong cong tan ((tran chau) OR (tranh chap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) OR (chieu sach)) - canh manh cua nong cong tan ((tran chau) or (tranh chap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) OR (chieu sach)) - canh manh cua nong cong tan ((tran chau) or (tranh chap))*.
