1. First install the jave environment jdk Download address I use the latest version. Sometimes the version corresponds to elastic search

2. Install elastic search Download address

3. Install the Laravel scout full-text search package. Here I use version 5.0.3, Tamayo / Laravel scout elastic. The version here is very important, otherwise I will make an error in a moment!

composer require laravel/scout=5.0.3

Build profile

php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

In this way, scout is installed. Please refer to the official tutorial

4. Because we want to use es as a search engine, we need to use a package called Tamayo / laravel scout elastic. 4.0 corresponds to 5.0.3. Don't get it wrong!

composer require tamayo/laravel-scout-elastic=4.0

5. Add the service provider to the providers array of config/app.php

// config/app.php
'providers' => [
    ...
    ScoutEngines\Elasticsearch\ElasticsearchProvider::class,
],

6. Configuration. Add the following code to the config/scout.php file. The default is the algolia engine. We want to use es as the engine

'driver' => env('SCOUT_DRIVER', 'elasticsearch'),
'elasticsearch' => [
    'index' => env('ELASTICSEARCH_INDEX', 'Your index name'),
    'hosts' => [
        env('ELASTICSEARCH_HOST', 'http://127.0.0.1:9200'),
    ],
],

7. Establish model and configure

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;  //It must be. It can be generated automatically

class Article extends Model
{
    //
    use Searchable;   //Be sure to have

    // Define the types in the index. As we mentioned above, you can type Understand as a data table. What we need to do now is to store all the fields we want to full-text search into es One of them is called'_doc'In the table.  
    public function searchableAs()  
    {  
        return 'articles';  
    }  
    // Define which fields to search  
    public function toSearchableArray()  
    {  
        return [  
            'user_title' => $this->title,  //user_name Prefix to distinguish. Because different tables may have the same fields. mysql The fields in are name,email,created_at. stay es We store user_name，user_email,user_created_at. It can be customized.
            'user_description' => $this->description,  
        ];  
    } 
}

8. When importing data, it's OK to add, update or delete the official document. The main thing is to configure es

php artisan scout:import "App\Models\Article"

9. Use search according to official scout, for example

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Article;

class TestController extends Controller
{
    public function test($value='')
    {
        return Article::search('ic')->paginate(5);
    }
}

Finally, summary, simple use, can be so, if there are other complex requirements, you can set it yourself!
