• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu xanh) or (chieu tinh)) - canh ((tranh chua) OR (tranh chap)) duong cong dan toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu tinh)) - canh ((tranh chua) OR (tranh chap)) duong cong dan toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu tinh)) - canh ((tranh chua) OR (tranh chap)) duong cong dan toan cau".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu tinh)) - canh ((tranh chua) OR (tranh chap)) duong cong dan toan cau*.
