php - PHP代码运行elasticsearch查询

Question

我是Elasticsearch的新手。我想使用elasticsearch搜索mysql dB。我想要并得到结果。我什至为此安装了elastica。但是我没有从此代码得到任何结果:

<?php
 require_once '/home/babloo/vendor/autoload.php';

$client = new Elastica_Client();
$index = $client->getIndex('jdbc');
$index->getType('jdbc');

$query_string = new Elastica_Query_QueryString('ashish');
$query_string->setFields(array('name'));    
$query = new Elastica_Query($query_string);

$index->refresh();
$searchResults = $index->search($query);
?>

我要去哪里错了？

Answer 1

改进语法并按照以下步骤操作:
1)将错误报告设置为开

   error_reporting(E_ALL);
   ini_set('display_errors', TRUE);
   ini_set('display_startup_errors', TRUE);
   session_start();

2)需要'vendor / autoload.php'; (使用 Composer 安装)

3)创建对象

   $client = new Elasticsearch\Client();
   $elasticaClient = new Elastica\Client();
   $reque=new Elastica\Request($elasticaClient);

4)程序示例

$index = $elasticaClient->getIndex('test');
$index->create(array(), true);
$type = $index->getType('test');
$type->addDocument(new Elastica\Document(1, array('username' => 'ruflin')));
$index->refresh();

$query = array(
    'query' => array(
        'query_string' => array(
            'query' => 'ruflin',
        )
    )
);
 //$typee =$reque->GET;
$path = $index->getName() . '/' . $type->getName() . '/_search';

$response = $elasticaClient->request($path, $reque::GET, $query);
$responseArray = $response->getData();

echo "<pre>";
print_r($responseArray);
