• Performing a fuzzy search may retrieve terms with similar spellings: ho chu tinh - ((((thanh trung) OR (thanh tung))) or (manh tung)) ve nhung cong tan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chu tinh - ((((thanh trung) OR (thanh tung))) OR (manh tung)) ve nhung cong tan toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chu tinh - ((((thanh trung) OR (thanh tung))) or (manh tung)) ve nhung cong tan toan cau*".
