• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach ((thu nghiep) OR (chu nghiep)) gio hoc ) or ( tu cach thai nhiem va hoc ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((thu nghiep) OR (chu nghiep)) gio hoc ) OR ( tu cach thai nhiem va hoc )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((thu nghiep) OR (chu nghiep)) gio hoc ) or ( tu cach thai nhiem va hoc ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach ((thu nghiep) OR (chu nghiep)) gio hoc ) or ( tu cach thai nhiem va hoc ))*.
