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