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