Hi @Cody Beard ,
It seems that a user with read-only access to a document folder within a SharePoint site is unable to search the library, even though the library settings allow it to appear in search results and read permissions are allowed to search the library. However, the site admin can search the library, indicating that the search function is working.
1.Try to crawl and re-index a site
Please refer to:https://learn.microsoft.com/en-us/sharepoint/make-site-content-searchable
2.Another reason could be file or folder-level security.
Please refer to this article:One of the reasons why you or your users might not see certain files or folders (while others can) is because those files and folders might have unique security and permissions set at file or folder level
I hope this information helps and have a great day!
