搜索过滤器在弹性搜索 PHP 中不起作用

Question

通过以下代码存储了一个新索引。

$data = array(
array("Name"=>"Norman","Email"=>"[e-mail]","Created"=>"2019-12-29 10:28:03","Modified"=>"2020-11-07 01:45:23"),
array("Name"=>"Drake","Email"=>"[e-mail]","Created"=>"2020-11-08 14:37:00","Modified"=>"2019-08-10 06:42:07"),
array("Name"=>"Wynne","Email"=>"[e-mail]","Created"=>"2019-05-19 23:30:42","Modified"=>"2019-06-09 08:13:58"),
array("Name"=>"Kirsten","Email"=>"[e-mail]","Created"=>"2020-01-09 23:34:19","Modified"=>"2020-04-16 10:23:07"),
array("Name"=>"Ainsley","Email"=>"[e-mail]","Created"=>"2019-01-22 18:14:39","Modified"=>"2019-09-02 18:44:30"),
array("Name"=>"Walker","Email"=>"[e-mail]","Created"=>"2020-11-05 23:04:46","Modified"=>"2020-01-03 09:29:36"),
array("Name"=>"Evelyn","Email"=>"[e-mail]","Created"=>"2020-06-28 13:23:09","Modified"=>"2019-04-02 05:41:33"),
array("Name"=>"James","Email"=>"[e-mail]","Created"=>"2020-04-20 10:15:54","Modified"=>"2020-07-22 12:04:49"),
array("Name"=>"Melvin","Email"=>"[e-mail]","Created"=>"2020-03-07 05:19:53","Modified"=>"2018-12-30 19:33:29"),
);
$hosts = ['http://localhost:9200'];
$client = ClientBuilder::create()->setHosts($hosts)->build();
$params = [
'index' => 'dummy_data',
'id'    => 'my_id',
'body'  => ['data' => $data]
];
$response = $client->index($params);

尝试按以下方法搜索第一条记录：

$params = [
'index' => 'dummy_data',
'body'  => [
'query' => [
'bool' => [
'must' => [
[ 'match' => [ 'data.Name' => 'Norman' ] ],
],
]
]
]
];
$results = $client->search($params);

问题是它返回查询仅与第一个匹配的所有记录。

请帮忙。

我猜你使用的是官方的Elasticsearch-PHP库。在这种情况下，看起来您正在将所有提供的数据索引为 1 个 id 为"my_id"的文档。这就是为什么当您的搜索匹配时，您可以取回整个数据集。

如果要同时为多个文档编制索引，则应查看bulk_index终结点。 以下是官方示例供参考：

for($i = 0; $i < 100; $i++) {
$params['body'][] = [
'index' => [
'_index' => 'my_index',
]
];
$params['body'][] = [
'my_field'     => 'my_value',
'second_field' => 'some more values'
];
}
$responses = $client->bulk($params);
