[Question] How to include custom attributes in search results?

[freeku]

Does anyone know how to include custom attributes from the index into the model when returning search results?

I've added custom fields in the index using toSearchableArray and these are showing up when returning the raw results. However, when I use the ->get(), the custom fields are not included in the model objects (as they are not in the underlying database table), and I can't seem to find out how to include them.

Thanks for the hint, Sergey!

For future reference for others looking into this, I've followed the approach outlined here #28 (comment) and added an additional function that's called in the getIterator() function:

private function mergeCustomFieldsIntoModels($eloquentHits, $raw){     
        return collect($eloquentHits)->map(function(Model $eloquentHit) use($raw){

            $raw = collect($raw)
                ->where('_source.__class_name', get_class($eloquentHit))
                ->where('_source.id', $eloquentHit->id)
                ->first()['_source'];
            
            $source = collect($raw);
            $eloquentHit->setAttribute('published_from', $source->get('published_from'));
            $eloquentHit->setAttribute('published_to', $source->get('published_to'));

            return $eloquentHit;
        })->all();
    }
