PHP中的Elasticsearch完成建议者查询 [英] Elasticsearch completion suggester query in PHP

问题描述

我找不到如何使用PHP（elasticsearch-php）中的完成建议器查询Elasticsearch的有效示例。

I was not able to find a working example on how to query Elasticsearch using the completion suggester in PHP (elasticsearch-php).

通过CURL查询，例如

Querying via CURL, e.g.

curl -X POST 'localhost:9200/tstidx/_suggest?pretty' -d '{
"try" : {
    "text" : "a",
    "completion" : {
        "field" : "suggest"
    }
}
}'

可以工作，所以唯一的问题是PHP中的查询部分。

works, so the only problem is the query part in PHP.

如何使用API​​通过完成建议器查询Elasticsearch？

How do I use the API to query Elasticsearch using the completion suggester?

推荐答案

PHP ES客户端具有一种名为 的方法建议 可以用于此目的：

The PHP ES client has a method called suggest that you can use for that purpose:

$params = [
    'index' => 'tstidx',
    'body' => [
        'try' => [
            'text' => 'a',
            'completion' => [ 'field' => 'suggest' ]
        ]
    ]
];

$client = ClientBuilder::create()->build();
$response = $client->suggest($params);
