How does deduplication work in the Knowledge and Library Hub?
A standard search of the Knowledge and Library Hub will search across a number of databases. (See What resources are searched through the Knowledge and Library Hub? to find out more.) This means that the same article might be retrieved from multiple sources. To avoid these multiple records appearing on your results list, the Knowledge Hub will remove duplicates showing you only the record with the highest relevance ranking. Deduplication is based on the following features:
When you run your search, you will initially see the total number of results retrieved across all the databases. If the content you retrieve appears in multiple sources, you may find that your actual list of search results is much smaller than the total hit count. If you want to check the total hits prior to deduplication, you can do this by checking the results database-by-database viewing the full "Limit by Databases" list (rebadged as Content Provided in the new Hub interface).
If your instance of the Knowledge Hub has an integrated library catalogue, these records are not deduplicated. You may see multiple copies of the same item if they appear in the source catalogue.
