Hi,

But Unable to Post image with it using postman.

Hello, I have been using the search APi attachments module to index file attachment content to search. However when I search it just returns the matching summary content and/or file attachment content together. I would like to just know what files were matched. Is there a module for this or a way to configure the search module for this?

Is it possible to add external PHP libraries to drupal8 auto-discover mechanism without composer?
