scout 服務配置，在 env 中增加配置項
// 驅動的host，若需賬密：http://es_username:password@127.0.0.1:9200SCOUT_ELASTIC_HOST=elasticsearch:9200// 驅動SCOUT_DRIVER=elastic// 隊列配置,數據量大時建議開啟SCOUT_QUEUE=true
composer require predis/predis
這里以 artisan 命令的方式配置 生成命令文件

}}生成 elatic Template 類似 mysql 表結構
php artisan es:init
更新 elatic 類型映射
php artisan elastic:update-mapping "App\Models\Article"
數據庫數據導入 elatic
php artisan scout:import "App\Models\Article"
PS: 其他命令
清空 elatic 數據
php artisan scout:flush "App\Models\Article"
$query = Article::search('二胡')
->paginateRaw(3,'article',1);
dd($query->items()['hits']);感謝各位的閱讀，以上就是“怎么在laravel中使用elaticsearch”的內容了，經過本文的學習后，相信大家對怎么在laravel中使用elaticsearch這一問題有了更深刻的體會，具體使用情況還需要大家實踐驗證。這里是億速云，小編將為大家推送更多相關知識點的文章，歡迎關注！
