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-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

['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

执行这个命令 生成 mapping
php artisan es:init
修改model支持 全文搜索
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();
