• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh doanh ((cua tong) OR (cua nong)) cong van ((toan cau) OR (tuan cu))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh doanh ((cua tong) OR (cua nong)) cong van ((toan cau) or (tuan cu))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - hanh doanh ((cua tong) OR (cua nong)) cong van ((toan cau) or (tuan cu))*.
