files search provider: display metadata title insead of filename in search results
search results from Files are currently displayed as filenames. these are often default (e.g. "document (12).pdf", "Untitled.docx"), or only say the id (e.g. DOI) but not the title, have underscores or dashes instead of spaces, something instead of slashes, are transliterated to latin or even percent-escaped, are either truncated or very long with the artist, year, album, publisher, and the website name on which the file was uploaded, have the extension which is usually of no use when searching.
i think it would be better if the result title was from the file's metadata instead of the filename
