• Performing a fuzzy search may retrieve terms with similar spellings: ho ((chieu sang) or (chinh sach)) - ((anh dang) OR (anh dung)) luan luong cong dan han tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (chinh sach)) - ((anh dang) OR (anh dung)) luan luong cong dan han tap*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chinh sach)) - ((anh dang) OR (anh dung)) luan luong cong dan han tap*".
