• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((thieu xanh) OR (hieu manh)) - ((nhanh tinh) OR (nhan sinh)) chat nhung cong san toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((thieu xanh) OR (hieu manh)) - ((nhanh tinh) or (nhan sinh)) chat nhung cong san toan cau~".
• Adding a wildcard symbol may retrieve word variants: toc ((thieu xanh) OR (hieu manh)) - ((nhanh tinh) or (nhan sinh)) chat nhung cong san toan cau*.
