Laravel如何用scout结合Elasticsearch实现长尾词全文搜索？

本文共计935个文字，预计阅读时间需要4分钟。

Laravel使用Scout集成Elasticsearch实现全文搜索的实现方法如下，适合分享给家人：

安装所需组件：

1.Composer

2.安装Scout扩展：`composer require tamayo/laravel-scout-elastic`

3.安装Scout核心库：`composer require laravel/scout`

配置步骤：

1.在`.env`文件中，设置Elasticsearch的连接信息，例如：

ELASTICSEARCH_HOST=your-elasticsearch-host ELASTICSEARCH_PORT=your-elasticsearch-port

2.在`config/scout.php`中，将Elasticsearch配置为默认搜索引擎：

php 'searchable'=> [ 'models'=> [ App\Models\YourModel::class=> [ 'engine'=> 'elasticsearch', ], ], ],

3.在`config/elastic.php`中，根据实际情况配置Elasticsearch客户端：

php 'connections'=> [ 'default'=> [ 'host'=> env('ELASTICSEARCH_HOST'), 'port'=> env('ELASTICSEARCH_PORT'), 'username'=> env('ELASTICSEARCH_USERNAME'), 'password'=> env('ELASTICSEARCH_PASSWORD'), ], ],

4.运行迁移和种子文件，以创建必要的索引和映射：

php artisan migrate php artisan db:seed

本文介绍了Laravel使用scout集成elasticsearch做全文搜索的实现方法，分享给大家，具体如下：

安装需要的组件

composer require tamayo/laravel-scout-elastic composer require laravel/scout

如果composer require laravel/scout 出现报错

Using version ^6.1 for laravel/scout ./composer.json has been updated Loading composer repositories with package information Updating dependencies (including require-dev) Your requirements could not be resolved to an installable set of packages. Problem 1 - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev]. - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev]. - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev]. - Conclusion: don't install laravel/scout 5.0.x-dev - Installation request for tamayo/laravel-scout-elastic ^4.0 -> satisfiable by tamayo/laravel-scout-elastic[4.0.0]. Installation failed, reverting ./composer.json to its original content.

那么使用命令

composer require laravel/scout ^5.0

修改一下配置文件（config/app.php），添加如下两个provider

'providers' => [ //es search 加上以下内容 Laravel\Scout\ScoutServiceProvider::class, ScoutEngines\Elasticsearch\ElasticsearchProvider::class, ]

添加完成，执行命令，生成config文件

php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

修改config/scout.php

'driver' => env('SCOUT_DRIVER', 'elasticsearch'), 'elasticsearch' => [ 'index' => env('ELASTICSEARCH_INDEX', '你的Index名字'), 'hosts' => [ env('ELASTICSEARCH_HOST', ''), ], ],

在.env 配置ES的 账号:密码@连接

ELASTICSEARCH_HOST=elastic:密码@你的域名.com:9200

创建一个生成mapping的命令行文件，到 app/Console/Commands

<?php namespace App\Console\Commands; use GuzzleHttp\Client; use Illuminate\Console\Command; class ESInit extends Command { protected $signature = 'es:init'; protected $description = 'init laravel es for news'; public function __construct() { parent::__construct(); } public function handle() { //创建template $client = new Client(['auth'=>['elastic', 'Wangcai5388']]); $url = config('scout.elasticsearch.hosts')[0] . '/_template/news'; $params = [ 'json' => [ 'template' => config('scout.elasticsearch.index'), 'settings' => [ 'number_of_shards' => 5 ], 'mappings' => [ '_default_' => [ 'dynamic_templates' => [ [ 'strings' => [ 'match_mapping_type' => 'string', 'mapping' => [ 'type' => 'text', 'analyzer' => 'ik_smart', 'ignore_above' => 256, 'fields' => [ 'keyword' => [ 'type' => 'keyword' ] ] ] ] ] ] ] ] ] ]; $client->put($url, $params); // 创建index $url = config('scout.elasticsearch.hosts')[0] . '/' . config('scout.elasticsearch.index'); $params = [ 'json' => [ 'settings' => [ 'refresh_interval' => '5s', 'number_of_shards' => 5, 'number_of_replicas' => 0 ], 'mappings' => [ '_default_' => [ '_all' => [ 'enabled' => false ] ] ] ] ]; $client->put($url, $params); } }

在kernel中注册这个命令

<?php namespace App\Console; use App\Console\Commands\ESInit; use Illuminate\Console\Scheduling\Schedule; use Illuminate\Foundation\Console\Kernel as ConsoleKernel; class Kernel extends ConsoleKernel { /** * The Artisan commands provided by your application. * * @var array */ protected $commands = [ ESInit::class ];

执行这个命令 生成 mapping

php artisan es:init

修改model支持 全文搜索

<?php namespace App\ActivityNews\Model; use App\Model\Category; use App\Star\Model\Star; use Illuminate\Database\Eloquent\Model; use Laravel\Scout\Searchable; class ActivityNews extends Model { use Searchable; protected $table = 'activity_news'; protected $fillable = [ 'type_id', 'category_id', 'title', 'sub_title', 'thumb', 'intro', 'star_id', 'start_at', 'end_at', 'content', 'video_url', 'status', 'is_open', 'is_top', 'rank', ]; public function star() { return $this->hasOne(Star::class, 'id', 'star_id'); } public function category() { return $this->hasOne(Category::class, 'id', 'category_id'); } public static function getActivityIdByName($name) { return self::select('id') ->where([ ['status', '=', 1], ['type_id', '=', 2], ['title', 'like', '%' . $name . '%'] ])->get()->pluck('id'); } }

导入全文索引信息

php artisan scout:import "App\ActivityNews\Model\ActivityNews"

测试简单的全文索引

php artisan tinker >>> App\ActivityNews\Model\ActivityNews::search('略懂皮毛')->get();
