require 'vendor/autoload.php';

$client = ElasticsearchClientBuilder::create()->build();

$params = [
    'index' => 'images',
    'body' => [
        'mappings' => [
            'properties' => [
                'image' => [
                    'type' => 'binary',
                ],
                'tags' => [
                    'type' => 'keyword',
                ],
            ],
        ],
    ],
];

$response = $client->indices()->create($params);

?? ?? ??? images?? ???? ???? image(??? ???? ???? ? ???) ? < code>tags (???? ???? ? ???? ?? ?? ??). images 的索引，并定義了兩個字段 image（用于存儲圖像數據）和 tags（用于標記圖像的相關標簽信息）。

四、上傳圖像數據
接下來，我們需要將圖像數據上傳到 Elasticsearch 中?？梢允褂?Elasticsearch 的 RESTful API，通過 HTTP 請求的方式將圖像數據發(fā)送給 Elasticsearch。

具體的代碼示例如下：

$imageData = file_get_contents('/path/to/image.jpg');

$params = [
    'index' => 'images',
    'body' => [
        'image' => base64_encode($imageData),
        'tags' => ['sunset', 'beach'],
    ],
];

$response = $client->index($params);

以上代碼片段將圖像數據以 base64 編碼方式存儲在 Elasticsearch 中，并使用 tags 字段關聯相關標簽信息。

五、圖像搜索
當圖像數據上傳完成后，我們可以通過 Elasticsearch 進行圖像搜索。使用 Elasticsearch 的搜索 API，我們可以利用圖像的特征進行搜索，并返回與搜索結果最匹配的圖像數據。

具體的代碼示例如下：

$params = [
    'index' => 'images',
    'body' => [
        'query' => [
            'match' => [
                'tags' => 'sunset',
            ],
        ],
    ],
];

$response = $client->search($params);

以上代碼片段將使用 tags 字段進行搜索，匹配標簽為 sunset
