下面由laravel教程栏目给大家介绍Laravel怎么使用scout集成elasticsearch做全文搜索，希望对需要的朋友有所帮助！

仅限于 es6.8版本
laravel 5.5版本

安装需要的组件

composer require tamayo/laravel-scout-elasticcomposer require laravel/scout

如果composer require laravel/scout 出现报错

Using version ^6.1 for laravel/scout./composer.json has been updatedLoading composer repositories with package informationUpdating 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

<?phpnamespace 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', 'yourPassword']]);        $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

<?phpnamespace 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

<?phpnamespace 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();
