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