• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu sang) OR (chieu xanh)) - thanh thanh cua trung cong tan ((doan tap) OR (doan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu sang) or (chieu xanh)) - thanh thanh cua trung cong tan ((doan tap) OR (doan cap))~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu sang) or (chieu xanh)) - thanh thanh cua trung cong tan ((doan tap) OR (doan cap))*.
