SharePoint Online Content Enhancement Web Service - Graph

Question

I have an immediate need to utilize the Microsoft Graph service (similar to the On Premise CEWS within SharePoint) called “content-events”. I’d like to be notified when new content is about to be added to the Index using the “Subscription Management” API of Graph so that I can “Add” additional crawled properties to enrich the content. I also need the content body (full text) of the document from a document library programically. What calls within the Graph API can be used to accomplish the same functionality of Content Enrichment Web Service?

Answer 1

Based on my researching, Content Enrichment is not available to SharePoint Online customers. Due to Graph interact with O365 product, so the Graph is not suitable for your current requirement. Of course, you can submit one feature request for it first.

Answer 2

Mike the contents-events service was a private internal preview that never made it out of there. There is work being done by Microsoft Search team to consider how this will be done. But to start with basic search extensibility needs to be tackled before tackling something like this. More news will come during Build 2019.
