Why are there different search results when searching First Search vs. searching in WorldCat Discovery?

Applies to
  • WorldCat Discovery
  • FirstSearch

This is because the search engine used for FirstSearch WorldCat and WorldCat Discovery is different.  The results will not be exactly the same.  WorldCat Discovery applies FRBR logic to searches and FirstSearch does not.
