• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chieu xanh)) - hanh tang ha thanh ((huong van) OR (huong dan)) tan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (chieu xanh)) - hanh tang ha thanh ((huong van) or (huong dan)) tan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) OR (chieu xanh)) - hanh tang ha thanh ((huong van) or (huong dan)) tan cau*.
