• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((hieu manh) OR (chieu sang)) - lanh manh cua nhung cong van ((khan ap) OR (khan cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((hieu manh) or (chieu sang)) - lanh manh cua nhung cong van ((khan ap) OR (khan cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((hieu manh) or (chieu sang)) - lanh manh cua nhung cong van ((khan ap) OR (khan cap))*.
