Duplicate content may be ingested from different sources. But you can remove (delete) documents from the pipeline using the Retire Knowledge Documents command. Retired documents will still exist in your data source.
To retire content from a particular source:
Navigate to Settings > Data Sources in the Aisera Admin UI.
Choose a Data Source with documents that you want to retire.
At the top of the Data Source Details window, click on the Retire Knowledge Documents button.
This icon will not appear if you have not ingested any knowledge articles
Retire Knowledge Documents
Select the checkboxes next to the documents you want to retire.
Select Documents to Retire
Click Ok to retire the selected documents.
The retired documents will not be used to server the user requests, and will no longer be ingested by the Data Source.
