I'm using sitecore 9.3.
I have a case where i have some content files (ex: PDF files) uploaded to sitecore media library and I have a search box component.
I need to configure my search box scope to search the content of those media library files. So if i wrote a search keyword,in the search box, that is included in the content of those uploaded PDF files, then i need to return this files somehow in the search results.
According to this Link, PDF files content is indexed by default in sitecore 9.3, but i'm not sure how to check these indexed content? and how to return its items in a search result.
