Seeking clarification of functionality & configuration

[kayakr]

Thank you for sharing this module. I have it working but I needed to change a few things:

1. From https://github.com/discoverygarden/dgi_image_discovery/blob/main/README.md?plain=1#L70 "Create a media item of type Image" suggested to me that a Image media type would be required, and that's what seems to be referenced in https://github.com/discoverygarden/dgi_image_discovery/blob/main/src/Plugin/search_api/processor/DgiImageDiscovery.php#L170 but the install hook dgi_image_discovery_update_8001() creates an Image field referencing a file not a media type.
   I needed to alter src/Plugin/search_api/processor/DgiImageDiscovery.php with:

171,176d170
<         if ($media instanceOf File) {
<           $uri = $media->getFileUri();
<           if ($uri) {
<             return $image_style->buildUrl($media->getFileUri());
<           }
<         }

2. Once I had dgi_image_discovery field added to the Solr index, the README.md suggests adding the virtual field "DGI Image Discovery Discovered Image" https://github.com/discoverygarden/dgi_image_discovery/blob/main/README.md?plain=1#L77 but that field is from Content datasource not the indexed field. I added "DGI Image Discovery" field to get URL from dgi_image_discovery in the search index, but then need to wrap that to become a thumbnail image, e.g. Rewrite results, "Override the output of this field with custom text", set Text=<img src="{{ dgi_image_discovery }}"/>.
