With External AutoFill Keyword Sets, you can configure an AutoFill Keyword Set that identifies a Primary Keyword Value from an external Data Source and pulls corresponding Secondary Keyword Values also from that external Data Source for indexing purposes.
For example, if users need to index documents with employee data, and an external database already contains all of the necessary values for indexing, you can configure an AutoFill Keyword Set that pulls the necessary Keyword Values from the external source.
Note:
Values for External AutoFill Keyword Sets will not reside in AutoFill Keyword Manager once configured. You must view the values for these sets externally.
