• Performing a fuzzy search may retrieve terms with similar spellings: theo chu tinh - ((((hanh mang) OR (nhanh mang))) or (nhanh lang)) luan nang cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu tinh - ((((hanh mang) OR (nhanh mang))) OR (nhanh lang)) luan nang cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu tinh - ((((hanh mang) OR (nhanh mang))) or (nhanh lang)) luan nang cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: theo chu tinh - ((((hanh mang) OR (nhanh mang))) or (nhanh lang)) luan nang cong dan toan cau*.
