I am working on SharePoint 2019 where I have created custom content type. This content type includes site columns. When I create Search Result Source and include this my custom content source and path as current site collection. It always return zero result.
But when I create same kind of Search Result Source with Task content type it return correct result.
I have run full crawl again. My search have every 5 minute incremental crawl. I have reset index search service. I have reset index list but it never return zero result. Let me know what I am doing wrong.
