OpenSearch:Démonstration de toutes les fonctionnalités de recherche

Cette rubrique décrit la configuration de l'environnement et fournit des exemples de code du SDK PHP pour la recherche de documents de base.

Créer le fichier d'en-tête Config

Le fichier Config sert de fichier d'en-tête pour les exemples ultérieurs de recherche et d'envoi de documents. Il contient les identifiants, l'endpoint, le nom de l'application et les options. Exemple :

<?php
// Import the header file.
require_once("../OpenSearch/Autoloader/Autoloader.php");
use OpenSearch\Client\OpenSearchClient;
// User credentials.
// Read the AccessKey ID and AccessKey secret from environment variables.
// Configure the environment variables before running the code example.
// Use the configured AccessKey ID.
$accessKeyId = getenv('ALIBABA_CLOUD_ACCESS_KEY_ID');
// Use the configured AccessKey secret.
$secret = getenv('ALIBABA_CLOUD_ACCESS_KEY_SECRET');
// Use the API endpoint for the region, as shown on the application Basic Information page.
$endPoint = '<region endPoint>';
// Use the application name.
$appName = '<app name>';
// Enable debug mode.
$options = array('debug' => true);
// Create the OpenSearchClient object.
$client = new OpenSearchClient($accessKeyId, $secret, $endPoint, $options);

Démonstration de toutes les fonctionnalités de recherche

Exemple :

<?php
header("Content-Type:text/html;charset=utf-8");
// Import the header file.
require_once("Config.inc.php");
use OpenSearch\Client\SearchClient;
use OpenSearch\Util\SearchParamsBuilder;
$searchClient = new SearchClient($client);
// Create the parameters object and specify its values.
$params = new SearchParamsBuilder();
$params->setStart(0);
$params->setHits(20);
// Set the application name.
$params->setAppName('your_app_name');
// Set the query.
$params->setQuery("name:'search'");
// Set the response format.
$params->setFormat("fulljson");
// Add sorting.
$params->addSort('id', SearchParamsBuilder::SORT_DECREASE);
$params->addSort('RANK', SearchParamsBuilder::SORT_DECREASE);
// Set the document filter.
$params->setFilter('id>0');
// Add the distinct clause.
$params->addDistinct(
    array('key' => 'cate_id', 'distTimes' => 1, 'distCount' => 1, 'reserved' => 'false')
);
// Add a summary.
$params->addSummary(
    array('summary_field' => 'name', 'summary_len' => 100, 'summary_ellipsis' => "...", 'summary_snippet' => 2, 'summary_element_prefix' => '<em>', 'summary_element_postfix' => '</em>')
);
//$params->addSummary(
//    array('summary_field' => 'name', 'summary_len' => 200)
//);
// Set custom parameters.
//$params->setCustomParam('a', 'b');
//$params->setCustomParam('c', 'd');
//$params->setRouteValue('1');

// Set from_request_id for the associated search request.
$params->setCustomParam('from_request_id','159851481919726888064081');

// Add the aggregate clause.
 $params->addAggregate(
     array('groupKey' => 'cate_id', 'aggFun' => 'count()', 'range' => '1', 'aggSamplerThresHold' => 1, 'aggSamplerStep' => 10, 'maxGroup' => 10)
 );
// $params->addAggregate(
//     array('groupKey' => 'cate_id', 'aggFun' => 'count()', 'range' => '1', 'aggFilter' => 'id>1', 'aggSamplerThresHold' => 1, 'aggSamplerStep' => 10, 'maxGroup' => 10)
// );
// Specify the first-rank expression.
$params->setFirstRankName('default');
// Specify the second-rank expression.
$params->setSecondRankName('default');
// Specify the fields to return.
$params->setFetchFields(array('id','name','phone','int_arr','literal_arr','float_arr','cate_id'));
// Add the raw_query parameter.
$params->setRawQuery("sample text");
// Execute the query and return information.
$ret = $searchClient->execute($params->build());
// Print the response.
print_r(json_decode($ret->result,true));
// Print debugging information.
echo $ret->traceInfo->tracer;
