• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - ((hanh tang) OR (anh tang)) luan ((nhung huong) or (nhung cong)) van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((hanh tang) OR (anh tang)) luan ((nhung huong) OR (nhung cong)) van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((hanh tang) OR (anh tang)) luan ((nhung huong) or (nhung cong)) van toan cau*".
