Cleaning Up Unused Field Resources
When using a Coveo Cloud index, you might find that you have many unused fields indexed, which can slow the overall performance of your index. To solve this issue, instead of manually deleting every unused field, you can clean up the unused field resources directly from the Sitecore UI.
This tool only deletes fields starting with f and ending with at least three digits (see The isExternal and isSourceSpecific Parameters in the fieldNames Table). If your unused fields are indexed as external, they will not be deleted.
- In Sitecore, access the Control Panel.
- Under Coveo Search, select Actions.
- Under Clean up Unused Resources, select Clean up.
In the Clean up Unused Resources window, select Clean up.
The cleaning process has started. To follow the progression, access the Sitecore logs. You should see something similar to this:
ManagedPoolThread #0 13:10:40 INFO Job started: Clean up unused resources. ManagedPoolThread #0 13:10:42 INFO 144 unused fields found in the organization. They will be deleted. ManagedPoolThread #0 13:10:44 INFO All unused fields deleted. ManagedPoolThread #0 13:10:44 INFO Job ended: Clean up unused resources. (units processed: )
