PHP代码运行elasticsearch查询

Question

Im newbie to elasticsearch. I wanted to search mysql dB using elasticsearch. I want and get the result. I even installed elastica for this. But Im not getting any results from this code:

<?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);
?>

where Am i going wrong?

Answer 1

Improve the syntax and follow the steps: 1) Do set error reporting ON

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

2) require 'vendor/autoload.php'; (Installed using composer)

3) Create Objects

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

4) Program Example

$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);
