Making an identity attribute searchable lists that in the fields to display as the non searchable attributes are stored in a CLOB object in DB, showing them in field to display would require quering the DB and parsing the the clob.
Hi @Remold I dont think there is a OOTB way to do this, as the Fields to Display are searchable attributes.
The only way to do this would be to do a custom plugin which would inject the data needed with a snippet.
