• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu sang) OR (chieu xanh)) - hanh tranh cua tong huong van ((phong tap) OR (phong tai))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu sang) OR (chieu xanh)) - hanh tranh cua tong huong van ((phong tap) or (phong tai))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu sang) OR (chieu xanh)) - hanh tranh cua tong huong van ((phong tap) or (phong tai))*.
