• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu sach - canh tranh ((quang dung) or (((cuong dung) OR (thong dung)))) cong san toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - canh tranh ((quang dung) OR (((cuong dung) OR (thong dung)))) cong san toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - canh tranh ((quang dung) or (((cuong dung) OR (thong dung)))) cong san toan cau*".
