I'm having an odd problem with a document library where the "find file" searchbar is not including results from the contents of the files in the library, only the titles. The library contains a custom content type based on the Document Set that consists of a nested series of folders with recognized filetypes inside. (.docx, xlxs, etc.) If I search for a document content term from the main site seach, it returns the correct result, so it seems everything was indexed correctly. The issue appears to be with the library search only. Can anyone help with this?
