• Performing a fuzzy search may retrieve terms with similar spellings: ((hoc thieu) or (theo chieu)) xanh - ((doanh doanh) OR (toan doanh)) luan cong dong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc thieu) OR (theo chieu)) xanh - ((doanh doanh) OR (toan doanh)) luan cong dong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) or (theo chieu)) xanh - ((doanh doanh) OR (toan doanh)) luan cong dong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (theo chieu)) xanh - ((doanh doanh) OR (toan doanh)) luan cong dong dan toan cau*.
