Create Ylaravel indexes and Templates ① create command (PHP artisan make:command E

Sinit) Initialize Es② modify esinit.php file (app/console/esinit.php), and you need to first introduce Guzzlehttp package composer require Guzzlehttp/guzzle
namespace 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 () {//create 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_temp

        ]

            ]
        ];

      

        $client->put ($url, $params); Create 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,],

        ' Enabled ' => false]]]]
        ];

       
    $client->put ($url, $params);
}③ mount <?php namespace App\console;
Use Illuminate\console\scheduling\schedule;

Use Illuminate\foundation\console\kernel as Consolekernel;
     Class Kernel extends Consolekernel {/** * Artisan commands by provided your.

* * @var array/protected $commands = [\app\console\commands\esinit::class];

④ calls es script PHP artisan es:init 4. Import Database and existing data ① modify data Model <?php APP;
Use App\model;
Use Illuminate\database\eloquent\builder;


Use laravel\scout\searchable;

    Class Posts extends Model {protected $table = ' Posts ';
    protected $guarded = [];


  Can inject the data field protected $fillable = [' title ', ' content '];  Use searchable;
    Defines the type public function Searchableas () in the index () {return ' post '; //define those fields that need to search for public function Tosearchablearray () {return [' title ' => $this-&G
     T;title, ' content ' => $this->content,]; }② Import model data php artisan scout:import "app\posts" Import authentication 127.0.0.1:9200/laravel/54/35-> record ID 5. Search page and logical display public functio

	N Search () {$this->validate (Request (), [' Query ' => ' required ']);

	$query = Request ([' query ']);

	$posts = App\posts::search ($query)->paginate (2);

Return view (' Post.search ', compact (' posts ')); }
