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