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