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