SharePoint Search & update of LikeCount
I'm not sure there will ever be a solution to this problem. I don't know how the crawler identifies which content needs an incremental crawl but I'm afraid that this would be a major change to the crawl-engine.
One way to work around this would be to trigger a Reindex for the Pages-Library on a regular base. But I'm not sure if you run into any throttling by Microsoft if you continously full-crawl several Libraries in SPO.
In our case we didn't find a solution to get it work, we'll remove the like count from the display template.
Markus Ihloff I would imagine there is a service called as part of the publishing process to flag the page as needing a re-crawl. There is a chance that the social service could just call the same code.
