Microsoft recently made some changes to the Microsoft Search that impacted the ability to display title metadata from SharePoint in modern search results (tenant search scope). It is now displaying the filename instead of the title in modern search results. The classic search results continues to work as expected (displays titles). We are unable to find any documentation on the recent change but was curious if anyone else had experienced the impact from this change? We've implemented some search adaptive cards to help minimize the impact but it only works for PDFs, not Office documents. Are there some options we could potentially explore that we haven't heard / seen yet that could help minimize the impact?
A few additional questions came to mind regarding this situation ---
1. Was it intended for filenames to only be displayed in modern search results? A few years ago, we were able to configure the title managed property on SharePoint online to display the title instead of the filename to meet our needs and it worked until the changes Microsoft made recently. This setup is similar what can be configured for SharePoint 2013 (Show more relevant Titles in search results in SharePoint 2013 plus some other improvements | Micros...).
2. Why does the title (metadata) still show in the site level search?
3. Why does the title (metadata) of the site page show in modern search results at the root (tenant search scope)? Isn't the library set up to store site pages and documents the same?
4. Are we moving away from using search schema in modern search results?
