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