Implement `updateIndexSettings` for algolia search

[yueyuzhao]

For now only MeilisearchEngine implements updateIndexSettings, but algolia also support index setting, see https://www.algolia.com/doc/api-reference/api-methods/set-settings/.

I see you made a PR so let's see how it goes. Thanks

Since the PR for this feature is closed, for those who might need this can:

1. create a custom search engine with method updateIndexSettings and extends AlgoliaEngine

   
   <?php
   namespace App;

use Laravel\Scout\Engines\AlgoliaEngine;

class AlgoliaSearchEngine extends AlgoliaEngine { /**

• Update an index's settings.
• @param string $name
• @param array $options

• @return \Algolia\AlgoliaSearch\Response\IndexingResponse */ public function updateIndexSettings(string $name, array $options = []) { $index = $this->algolia->initIndex($name);

  return $index->setSettings($options);

  } }

  
  2. register the search engine, I did this in `boot` of `AppServiceProvider`:
  ```php
  <?php

namespace App\Providers;

use Algolia\AlgoliaSearch\SearchClient as Algolia; use Algolia\AlgoliaSearch\Config\SearchConfig; use Algolia\AlgoliaSearch\Support\UserAgent; use App\AlgoliaSearchEngine; use Illuminate\Support\ServiceProvider; use Laravel\Scout\EngineManager; use Laravel\Scout\Scout;

class AlgoliaServiceProvider extends ServiceProvider { /**

• Register services. */ public function register(): void { // }

  /**

• Bootstrap services. */ public function boot(): void { resolve(EngineManager::class)->extend('algolia', function () { UserAgent::addCustomUserAgent('Laravel Scout', Scout::VERSION);

      $defaultAlgoliaHeaders = function () {
          if (!config('scout.identify')) {
              return [];
          }
  
          $headers = [];
  
          if (!config('app.debug') &&
              filter_var($ip = request()->ip(), FILTER_VALIDATE_IP, FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE)
          ) {
              $headers['X-Forwarded-For'] = $ip;
          }
  
          if (($user = request()->user()) && method_exists($user, 'getKey')) {
              $headers['X-Algolia-UserToken'] = $user->getKey();
          }
  
          return $headers;
      };
  
      $config = SearchConfig::create(
          config('scout.algolia.id'),
          config('scout.algolia.secret')
      )->setDefaultHeaders(
          $defaultAlgoliaHeaders()
      );
  
      if (is_int($connectTimeout = config('scout.algolia.connect_timeout'))) {
          $config->setConnectTimeout($connectTimeout);
      }
  
      if (is_int($readTimeout = config('scout.algolia.read_timeout'))) {
          $config->setReadTimeout($readTimeout);
      }
  
      if (is_int($writeTimeout = config('scout.algolia.write_timeout'))) {
          $config->setWriteTimeout($writeTimeout);
      }
  
      if (is_int($batchSize = config('scout.algolia.batch_size'))) {
          $config->setBatchSize($batchSize);
      }
  
      return new AlgoliaSearchEngine(Algolia::createWithConfig($config), config('scout.soft_delete'));
  });

  } }

  
  4. add index settings in `config/scout.php` for algolia.
  5. update algolia index settings by running: `php artisan scout:sync-index-settings`
