Indexes settings using model

First create a command file:

php artisan make:command ScoutSync

The content of app/Console/Commands/ScoutSync.php

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Laravel\Scout\EngineManager;
use Laravel\Scout\Searchable;
use MeiliSearch\Client;

class ScoutSync extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'scout:sync {model? : Class name of model to update settings}';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Sync your configuration with meilisearch';

    /** 
     * The meilisearch client.
     * 
     * @var Client
     */
    private $client;

    public function __construct()
    {
        parent::__construct();
        $this->client = app(EngineManager::class)->driver('meilisearch');
    }

    /**
     * Execute the console command.
     */
    public function handle(): void
    {
        if ($namespace = $this->argument('model')) {
            $model = new $namespace;
            $this->syncModel($model);
            return;
        }

        $this->syncAll();
    }

    private function syncModel($model): void
    {
        if ($this->hasSettings($model)) {
            $this->updateSettings($model);
        }
    }

    private function syncAll(): void
    {
        collect(scandir(app_path('Models')))->each(
            function ($path) {
                if ($path === '.' || $path === '..') {
                    return true;
                }

                $namespace = 'App\Models\\' . substr($path, 0, -4);
                $model = new $namespace;
                $this->syncModel($model);
            }
        );
    }

    private function updateSettings($model): void
    {
        $index = $this->client->index($model->searchableAs());
        collect($model->meilisearchSettings)->each(
            function ($value, $key) use ($index) {
                $status = $index->{$key}($value);
                $this->line("{$key} has been updated, updateId: {$status['updateId']}");
            }
        );
    }

    private function hasSettings($model): bool
    {
        return in_array(Searchable::class, class_uses($model)) && property_exists($model, 'meilisearchSettings');
    }
}

Then in your model you can add a new class property with the configuration

    public $meilisearchSettings = [
        'updateAttributesForFaceting' => [
            'title',
            'genres',
        ],
        'updateSynonyms' => [
            'movie' => ['video'],
            'video' => ['movie'],
        ],
        'updateSearchableAttributes' => ['title']
    ];

Here is the list of all available settings:

• updateSynonyms
• updateStopWords
• updateAttributesForFaceting
• updateRankingRules
• updateDistinctAttribute
• updateDisplayedAttributes
• updateSearchableAttributes
