• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chieu xanh) or (chieu sang)) - ((doanh doanh) OR (doanh hoan)) cua bang cong dan thi cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sang)) - ((doanh doanh) OR (doanh hoan)) cua bang cong dan thi cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) or (chieu sang)) - ((doanh doanh) OR (doanh hoan)) cua bang cong dan thi cao*".
