# 例

PHP で Apache Solr エクステンションを使用する方法の例

例1 ブートストラップ・ファイルの内容

`<?php
/* Solr サーバーのドメイン名 */
define('SOLR_SERVER_HOSTNAME', 'solr.example.com');
/* セキュアなモードで動作するかどうか */
define('SOLR_SECURE', true);
/* 接続する HTTP ポート */
define('SOLR_SERVER_PORT', ((SOLR_SECURE) ? 8443 : 8983));
/* HTTP Basic 認証ユーザー名 */
define('SOLR_SERVER_USERNAME', 'admin');
/* HTTP Basic 認証パスワード */
define('SOLR_SERVER_PASSWORD', 'changeit');
/* HTTP 接続タイムアウト */
/* HTTP データ転送動作に許される、秒単位の最大時間。既定値は３０秒 */
define('SOLR_SERVER_TIMEOUT', 10);
/* PEM 形式のプライベートキーとプライベート証明書に対するファイル名（その順序で連結されます） */
define('SOLR_SSL_CERT', 'certs/combo.pem');
/* PEM 形式のプライベート証明書のみに対するファイル名 */
define('SOLR_SSL_CERT_ONLY', 'certs/solr.crt');
/* PEM 形式のプライベートキーに対するファイル名 */
define('SOLR_SSL_KEY', 'certs/solr.key');
/* PEM 形式のプライベートキー・ファイルに対するパスワード */
define('SOLR_SSL_KEYPASSWORD', 'StrongAndSecurePassword');
/* 同等であることを証明する、一つ以上の CA 証明書を持つファイル名 */
define('SOLR_SSL_CAINFO', 'certs/cacert.crt');
/* 同等であることを証明する、複数の CA 証明書があるディレクトリ名 */
define('SOLR_SSL_CAPATH', 'certs/');
?>`

例2 インデックスに文書を追加

`<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$doc = new SolrInputDocument();
$doc->addField('id', 334455);
$doc->addField('cat', 'Software');
$doc->addField('cat', 'Lucene');
$updateResponse = $client->addDocument($doc);
print_r($updateResponse->getResponse());
?>`

上の例の出力は、 たとえば以下のようになります。

    SolrObject Object
    (
        [responseHeader] => SolrObject Object
            (
                [status] => 0
                [QTime] => 446
            )

    )

例3 ある文書を他の文書にマージ

`<?php
include "bootstrap.php";
$doc = new SolrDocument();
$second_doc = new SolrDocument();
$doc->addField('id', 1123);
$doc->features = "PHP Client Side";
$doc->features = "Fast development cycles";
$doc['cat'] = 'Software';
$doc['cat'] = 'Custom Search';
$doc->cat = 'Information Technology';
$second_doc->addField('cat', 'Lucene Search');
$second_doc->merge($doc, true);
print_r($second_doc->toArray());
?>`

上の例の出力は、 たとえば以下のようになります。

                            )

                    )

                [1] => SolrDocumentField Object
                    (
                        [name] => id
                        [boost] => 0

                            )

                    )

                [2] => SolrDocumentField Object
                    (
                        [name] => features
                        [boost] => 0
                        [values] => Array
                            (
                                [0] => PHP Client Side
                                [1] => Fast development cycles
                            )

                    )

            )

    )

例10 簡単なファセット例 - mincount を越える任意の項目と共に

`<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
);
$client = new SolrClient($options);
$query = new SolrQuery('*:*');
$query->setFacet(true);
$query->addFacetField('cat')->addFacetField('name')->setFacetMinCount(2)->setFacetMinCount(4, 'name');
$updateResponse = $client->query($query);
$response_array = $updateResponse->getResponse();
$facet_data = $response_array->facet_counts->facet_fields;
print_r($facet_data);
?>`

例14 Solr Real Time Get (RTG) の例 SolrClient::getById()

`<?php
include "bootstrap.php";
$options = array
(
'hostname' => SOLR_SERVER_HOSTNAME,
'login' => SOLR_SERVER_USERNAME,
'password' => SOLR_SERVER_PASSWORD,
'port' => SOLR_SERVER_PORT,
'path' => SOLR_SERVER_PATH
);
$client = new SolrClient($options);
$response = $client->getById('GB18030TEST');
print_r($response->getResponse());
?>`
