laravel使用ElasticSearch进行搜索

1.安装elasticsearch和ik插件①elasticsearch集成包（包括ik中文插件）安装地址：https://github.com/medcl/elasticsearch-rtf②测试安装启动elasticSearch：bin/elasticSearch -d③测试是否安装成功127.0.0.1:92002.ElasticSearch的laravel scout 包的安装（1）①安装laravel/scoutcomposer require laravel/scout②将 ScoutServiceProvider 添加到你的配置文件 config/app.php 的 providers 数组中：Laravel\Scout\ScoutServiceProvider::class,③注册好 Scout 的服务提供器之后，你还需使用Artisan 命令 vendor:publish 生成 Scout 的配置文件。这个命令会在你的 config 目录下生成 scout.php 配置文件：php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"（2）安装scout的es驱动（https://github.com/ErickTamayo/laravel-scout-elastic）①composer require tamayo/laravel-scout-elastic②You must add the Scout service provider and the package service provider in your app.php config:// config/app.php'providers' => [    ...    Laravel\Scout\ScoutServiceProvider::class,    ...    ScoutEngines\Elasticsearch\ElasticsearchProvider::class,]③Setting up Elasticsearch configurationYou must have a Elasticsearch server up and running with the index you want to use createdIf you need help with this please refer to the Elasticsearch documentationAfter you've published the Laravel Scout package configuration:// config/scout.php// Set your driver to elasticsearch    'driver' => env('SCOUT_DRIVER', 'elasticsearch'),...    'elasticsearch' => [        'index' => env('ELASTICSEARCH_INDEX', 'laravel'),        'hosts' => [            env('ELASTICSEARCH_HOST', 'http://localhost'),        ],    ],3.创建ylaravel的索引和模板①创建command(php artisan make:command ESInit)初始化ES②修改ESInit.php文件（app/console/ESInit.php），同时需要先引入GuzzleHttp包composer require Guzzlehttp/guzzle<?phpnamespace App\Console\Commands;use GuzzleHttp\Client;use Illuminate\Console\Command;class ESInit extends Command{    /**     * The name and signature of the console command.     *     * @var string     */    protected $signature = 'es:init';    /**     * The console command description.     *     * @var string     */    protected $description = 'init laravel es for post';    /**     * Create a new command instance.     *     * @return void     */    public function __construct()    {        parent::__construct();    }    /**     * Execute the console command.     *     * @return mixed     */    public function handle()    {        //创建template        $client = new Client();        $url = config('scout.elasticsearch.hosts')[0] . '/_template/tmp';        $client->delete($url);        $params = [            'json' => [                    'template' => config('scout.elasticsearch.index'),                ],                'mappings' => [                    '_default_' => [                        'dynamic_templates' => [                            [                                'strings' => [                                    'match_mapping_type' => 'string',                                    'mapping' => [                                        'type' => 'text',                                        'analyzer' => 'ik_smart',                                        'fields' => [                                            'keyword' => [                                                'type' => 'keyword'                                            ]                                        ]                                    ]                            ]                        ]                    ]                ]            ]        ];        $client->put($url, $params);              // 创建index        $url = config('scout.elasticsearch.hosts')[0] . '/' . config('scout.elasticsearch.index');        $client->delete($url);        $params = [            'json' => [                'settings' => [                    'refresh_interval' => '5s',                    'number_of_shards' => 1,                    'number_of_replicas' => 0,                ],                'mappings' => [                    '_default_' => [                        '_all' => [                            'enabled' => false                        ]                    ]                ]            ]        ];        $client->put($url, $params);           }}③挂载<?phpnamespace App\Console;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 = [        \App\Console\Commands\ESInit::class    ];④调用es脚本php artisan es:init4.导入数据库和已有的数据①修改数据模型<?phpnamespace App;use App\Model;use Illuminate\Database\Eloquent\Builder;// use Laravel\Scout\Searchable;class Posts extends Model{    protected $table = 'posts';    protected $guarded = [];    // 可以注入是的数据字段    protected $fillable = ['title', 'content'];    use Searchable;     // 定义索引里面的类型    public function searchableAs()    {        return 'post';    }     // 定义有那些字段需要搜索     public function toSearchableArray()    {        return [             'title' => $this->title,             'content' => $this->content,         ];     }②导入模型数据php artisan scout:import "App\Posts"导入验证127.0.0.1:9200/laravel/54/35->记录的id5.搜索页面和逻辑的展示public function search(){$this->validate(request(), ['query' => 'required']);$query = request(['query']);$posts = App\Posts::search($query)->paginate(2);return view('post.search', compact('posts'));}
