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