• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chiet tach) OR (chieu sach)) - hanh trang cua ((nhan trong) OR (nhuan trong)) sinh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (chieu sach)) - hanh trang cua ((nhan trong) OR (nhuan trong)) sinh toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (chieu sach)) - hanh trang cua ((nhan trong) OR (nhuan trong)) sinh toan cau*.
