• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) or (chieu tinh)) - hanh trong quan cong ((thuong doan) OR (phuong doan)) tuan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - hanh trong quan cong ((thuong doan) OR (phuong doan)) tuan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - hanh trong quan cong ((thuong doan) OR (phuong doan)) tuan cau*".
