# Pushing related entries to an Algolia index

Transform entry data before indexing to Algolia, including pushing related entries alongside each record in the index.

Consider the following index in `config/statamic/search.php`:

```php
'videos' => [
    'driver' => 'algolia',
    'searchables' => 'collection:videos',
    'fields' => ['title', 'artwork', 'tags', 'description', 'id', 'author'],
],
```

Here we have 6 fields that we wish to be in our Algolia index. In this instance `author` is a related entry in another collection. If we were to update the index currently, all we'd see is the entry id from the related collection which isn't very helpful to our Algolia search results.

Enter `transformers` - "robots in disguise", I know you just sang that in your head!

If we update our index to include transformers:

```php
'videos' => [
    'driver' => 'algolia',
    'searchables' => 'collection:videos',
    'fields' => ['title', 'artwork', 'tags', 'description', 'id', 'author'],
    'transformers' => [
        'author' => function ($author) {
            $entry = Entry::find($author);
            return [
                'author_name' => "{$entry->author_first_name} {$entry->title}",
            ];
        }
    ]
],
```
We pass the entry id into a function, lookup the entry by its id, we can then push the author name - where our blueprint has `author_first_name` as a field of course.

Happy transforming.
