elasticsearchHow can I integrate Elasticsearch into a Yii2 application?
Integrating Elasticsearch into a Yii2 application is a straightforward process. The following steps will help you get started:
- Install the elasticsearch-php library:
composer require elasticsearch/elasticsearch
- Create a new component in your Yii2 application's
config/main.php
file:
'components' => [
...
'elasticsearch' => [
'class' => 'yii\elasticsearch\Connection',
'nodes' => [
['http_address' => '127.0.0.1:9200'],
],
],
...
],
- Create a
Search
model class in your application that extendsyii\elasticsearch\ActiveRecord
:
<?php
namespace app\models;
use yii\elasticsearch\ActiveRecord;
class Search extends ActiveRecord
{
public function attributes()
{
return ['title', 'content'];
}
}
- Create an action in the controller to perform the search:
public function actionSearch()
{
$query = Yii::$app->request->get('query');
$results = Search::find()->query([
'multi_match' => [
'query' => $query,
'fields' => ['title', 'content']
]
])->all();
return $this->render('search', [
'results' => $results
]);
}
- Create a view file to render the search results:
<?php foreach ($results as $result): ?>
<h2><?= $result->title ?></h2>
<p><?= $result->content ?></p>
<?php endforeach; ?>
These steps should get you up and running with Elasticsearch in your Yii2 application.
