大量のデータの検索リクエストを処理するために php Elasticsearch を最適化するにはどうすればよいですか?

$params = []; // 定义一个空数组
foreach($data as $item) {
    $params['body'][] = [
        'index' => [
            '_index' => 'your_index_name',
            '_type' => 'your_type_name',
        ]
    ];
    $params['body'][] = $item;
}

$response = $client->bulk($params); // 批量写入数据

$params = [
    'index' => 'your_index_name',
    'body' => [
        'settings' => [
            'number_of_shards' => 5, // 分片数
            'number_of_replicas' => 1, // 副本数
        ]
    ]
];

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

$params = [
    'index' => 'your_index_name',
    'name' => 'your_alias_name',
];

$response = $client->indices()->putAlias($params); // 创建索引别名

$params = [
    'index' => 'your_index_name',
    'type' => 'your_type_name',
    'body' => [
        'suggest' => [
            'your_suggestion_name' => [
                'text' => 'your_search_keyword',
                'term' => [
                    'field' => 'your_field_name',
                ],
            ],
        ],
    ],
];

$response = $client->search($params); // 搜索建议
