• Performing a fuzzy search may retrieve terms with similar spellings: ho chiet tach - anh dang ((cua khong) or (cua phuong)) thong van ((toan cau) OR (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chiet tach - anh dang ((cua khong) OR (cua phuong)) thong van ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - anh dang ((cua khong) or (cua phuong)) thong van ((toan cau) OR (toan cao))*".
