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