• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sach) or (chieu sang)) - ((hanh trung) OR (manh trung)) cua dang cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chieu sang)) - ((hanh trung) OR (manh trung)) cua dang cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (chieu sang)) - ((hanh trung) OR (manh trung)) cua dang cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (chieu sang)) - ((hanh trung) OR (manh trung)) cua dang cong dan toan cau*.
