• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sang)) - thanh truong ((quan nhung) OR (qua nhung)) cong bang toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - thanh truong ((quan nhung) or (qua nhung)) cong bang toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - thanh truong ((quan nhung) or (qua nhung)) cong bang toan cau*.
