• Performing a fuzzy search may retrieve terms with similar spellings: hoc thieu sach - thanh truong va nhung cong ((((dan toan) OR (manh toan))) or (van than)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu sach - thanh truong va nhung cong ((((dan toan) OR (manh toan))) OR (van than)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu sach - thanh truong va nhung cong ((((dan toan) OR (manh toan))) or (van than)) cau*".
