Hybrid Search SharePoint On-Prem Property Bag Property not Creating Crawled Properties

Question

I have setup Cloud Hybrid Search and did a full crawl on on-prem Local SharePoint Sites content source.

After successful crawl completion I see all crawled properties for site/list columns created under online search schema. But I don't see the crawled properties for the on-prem sites property bag properties.

I also created a new property bag properties on on-prem sites and did a full crawl again. I don't see these properties either.

Do I need to take care of any additional steps or is this an issue?

Can someone give me your thoughts if you already gone through this scenario

Answer 1

I did set the property bag properties Indexed explicitly and did a full crawl again. It started showing up the crawled properties.

Example:

Set-PnPPropertyBagValue -Key "<<Property Name>>" -Value "<<property value>>" -Indexed
