Delete (Indexes)

Description

License:

The active portal account must be licensed with the ArcGIS Knowledge user type extension to use Knowledge Graph Server services.

The delete operation is available for the indexes resource associated with a named type in a knowledge graph service's data model. With this operation, you can delete an index from a field associated with an entity type or relationship type in the data model. Deleting an index will prevent you from searching content stored in this field using the search operation on the knowledge graph service's graph resource.

Identify the specific type whose indexes you want to modify by specifying the type name. Use the data model query operation to learn about the item types that are defined in the schema and the fields already defined for that type.

You must have sufficient privileges to edit content and editing must be enabled for the knowledge graph service for this operation to be successful. You can enable editing for a knowledge graph service in the same way that you enable it for a hosted feature layer. The knowledge graph service's strict property must not be set to true, which indicates the data model cannot be modified.
