• Performing a fuzzy search may retrieve terms with similar spellings: (( ((vu nhanh) OR (vu khanh)) va nghiep du hoc ) or ( tu cach ta nghiem d hoc ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((vu nhanh) OR (vu khanh)) va nghiep du hoc ) OR ( tu cach ta nghiem d hoc ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((vu nhanh) OR (vu khanh)) va nghiep du hoc ) or ( tu cach ta nghiem d hoc ))*".
