• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu xanh - ((danh trung) or (tdanh trung)) cua ((khong cong) OR (thong cong)) van luan ban~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu xanh - ((danh trung) OR (tdanh trung)) cua ((khong cong) OR (thong cong)) van luan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((danh trung) or (tdanh trung)) cua ((khong cong) OR (thong cong)) van luan ban*".
