Modern Library Search

[Laura Sunday]

I have a client that is requesting the search results from library level only return folder content type.  I have MS support saying this is not possible.  Does anyone know of a way to filter the search results from a modern library to  only show folders and not the content in the folders?

Are you talking about search in modern document libraries? If so, what support has told you is correct so your options here can be:
(1) Rely on the filters panel in the document library
(2) Develop a custom search solution that can be called from your document library...for instance, a SPFx Extension that opens a side panel or a popup where you can search by folder content type

There is an open source solution available at: https://github.com/estruyf/react-handlebars-search. Note that this will not replace the existing search boxes but is something you could add to a page and point your users to it. This web part more or less emulates what we had available in classic.
