 * Search Files

 * Search files and folders by name, metadata and content in your OneDrive, or in another drive when `drive_id` is set. Results come from the search index, so a file created seconds ago may not appear yet. Pass the returned `@odata.nextLink` as `next_link` for the next page. Requires Files.Read (covered by the default Files.ReadWrite); a drive that is not your own needs Files.Read.All.
