• Performing a fuzzy search may retrieve terms with similar spellings: doi ((chieu xanh) OR (chieu sang)) - ((hanh trung) or (canh tranh)) cua dung phuong doan than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chieu xanh) OR (chieu sang)) - ((hanh trung) OR (canh tranh)) cua dung phuong doan than cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu xanh) OR (chieu sang)) - ((hanh trung) or (canh tranh)) cua dung phuong doan than cau*".
