• Performing a fuzzy search may retrieve terms with similar spellings: theo ((tieu tinh) or (lieu tinh)) - canh tranh ((van nhung) OR (van nhuong)) cong manh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu tinh) OR (lieu tinh)) - canh tranh ((van nhung) OR (van nhuong)) cong manh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu tinh) or (lieu tinh)) - canh tranh ((van nhung) OR (van nhuong)) cong manh toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu tinh) or (lieu tinh)) - canh tranh ((van nhung) OR (van nhuong)) cong manh toan cau*.
