• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - canh doanh ((luan dang) OR (luan nang)) cong tan ((toan tai) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sang - canh doanh ((luan dang) OR (luan nang)) cong tan ((toan tai) or (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - canh doanh ((luan dang) OR (luan nang)) cong tan ((toan tai) or (toan ban))*.
