Written in front
Elasticsearch (hereinafter referred to as es) is a real-time distributed search and analysis engine.
In terms of search engines, there are not only Elasticsearch, but also Algolia mentioned in another article, but also sphinx, Solr, etc. There will be no evaluation and comparison here. This article mainly introduces how to use Elasticsearch in laravel.
The first choice must be Elasticsearch installed.
This article is based on laravel5.5, other versions are similar.
Preparation
Install dependent packages through composer
composer require laravel/scout composer require tamayo/laravel-scout-elastic
Basic configuration
In config/app Add the service provider to the providers array in the .php file
// config/app.php
'providers' => [
// ...
Laravel\Scout\ScoutServiceProvider::class,
// ...
ScoutEngines\Elasticsearch\ElasticsearchProvider::class,
],Use the following command to generate the scout configuration file
php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"
Add the elasticsearch configuration to config/scout.php
'elasticsearch' => [
'index' => env('ELASTICSEARCH_INDEX', 'laravel'),
'hosts' => [
env('ELASTICSEARCH_HOST', 'http://localhost:9200'),
],
],Then we open the .env file and add the configuration of scout and elasticsearch
# scout配置 SCOUT_DRIVER=elasticsearch SCOUT_PREFIX= # elasticsearch 配置 ELASTICSEARCH_INDEX=esdemo # elasticsearch 地址 ELASTICSEARCH_HOST=http://172.30.6.1:9200
Create index
Create the model and fill in the data
Create model app/Student.php. To facilitate subsequent testing, please create tables and fill in data first. You can manually add data using sql statements, or use laravel to automatically migrate and fill data.
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;
/**
* 学生模型
*/
class Student extends Model
{
use Searchable;
/**
* 索引名称
*
* @return string
*/
public function searchableAs()
{
return 'students_index';
}
/**
* 可搜索的数据索引
*
* @return array
*/
public function toSearchableArray()
{
$array = $this->toArray();
// Customize array...
return $array;
}
}Import all existing records into the search index
php artisan scout:import "App\Student"
Is the import successful?
php artisan scout:import "App\Student" Imported [App\Student] models up to ID: 500 Imported [App\Student] models up to ID: 1000 Imported [App\Student] models up to ID: 1500 Imported [App\Student] models up to ID: 2000 Imported [App\Student] models up to ID: 2500 Imported [App\Student] models up to ID: 3000 Imported [App\Student] models up to ID: 3500 Imported [App\Student] models up to ID: 4000 Imported [App\Student] models up to ID: 4500 Imported [App\Student] models up to ID: 5000 Imported [App\Student] models up to ID: 5500 Imported [App\Student] models up to ID: 6000 Imported [App\Student] models up to ID: 6500 Imported [App\Student] models up to ID: 7000 Imported [App\Student] models up to ID: 7500 Imported [App\Student] models up to ID: 8000 Imported [App\Student] models up to ID: 8500 Imported [App\Student] models up to ID: 9000 Imported [App\Student] models up to ID: 9500 Imported [App\Student] models up to ID: 10000 All [App\Student] records have been imported.
We visit es, http://172.30.6.1:9200/esdemo/students_index/_search
Do you already have the students_index index data you just imported?
Done
$studens = App\Student::search('成燕')->get(); dd($studens);
You can try filling in a million pieces of data. Is the retrieval speed much faster than querying the database directly?
