Reading the article How to: Use the Content Enrichment web service callout for SharePoint Server it looks like I need to develop my own WCF Web Service to use the Content Enrichment. The list of prerequisites clearly states I need:
- Search in SharePoint 2013
- Visual Studio 2010 or similar .NET Framework–compatible development tool
- Administrator privileges on your SharePoint Server 2013 installation
- A server on which you can host the service with IIS
I haven't found a way to use the Content Enrichment without custom code. Is it possible to use Content Enrichment just using PowerShell in a farm where I have Shell Access and administrator permissions on the SQL Server?
