Elasticsearch-PHP 7返回给定映射的所有文档

Question

摘要

未能使用ElasticSearch-PHP7包从我的ElasticSearch实例中获取任何/所有文档。

当我运行Curl查询时，工作正常。所以我知道我把文件插好了。意味着文件确实存在。

卷曲成功

Curl调用

curl -X GET -u elastic:changeme 'ltr-elasticsearch:9200/experiences_1621701804/region/_search?pretty'

{
    "took": 58,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 100,
        "max_score": 1,
        "hits": [
            {
                "_index": "experiences_1621701804",
                "_type": "region",
                "_id": "14",
                "_score": 1,
                "_source": {
                    "id": 14,
                    "name": "Dallas",
                    "active": "1",
                    "image": {
                        "domain": null,
                        "original": "https://d2l34t1fl9ccx8.cloudfront.net/media/image/d/a/dallas.jpg",
                        "small": "https://d2l34t1fl9ccx8.cloudfront.net/media/image/d/a/dallas.jpg",
                        "thumbnail": "https://d2l34t1fl9ccx8.cloudfront.net/media/image/d/a/dallas.jpg"
                    }
                }
            }
            // many more document results show up here
        ]
    }
};

Elasticsearch-PHP 7搜索手册

// Build Params with Raw JSON
$params = [
    'index' => 'experiences_1621701804',
    'type' => 'region',
    'body'  => '{
        "query": {
            "match_all": {}
        }
    }',
];

// Also tried
$params = [
    'index' => 'experiences_1621701804',
    'type' => 'region',
    'body'   => [
        'query' => [
            'match_all' => new \stdClass()
        ]
    ]
];

// Trigger Search
$results = $esClientBuilder->search($params);
print_r($results);

更新了可能的解决方案？

菜鸟的动作，我应该比较一下版本。对于elasticsearch/elasticsearch包有一个版本映射。

https://www.elastic.co/guide/en/elasticsearch/client/php-api/current/installation.html

我目前在elasticsearch/elasticsearch的第5.2版。

看起来v5不支持match_all吗？对我来说真的很奇怪。我认为一个基本的特点是获得所有的文件。我知道这是一个搜索工具，也许它只是专注于过滤的搜索结果。而且有可能它只是以一种不同的方式处理它，没有文件记录。

v5：https://www.elastic.co/guide/en/elasticsearch/client/php-api/5.x/_match_query.html

我目前被排除在我的工作VPN之外，无法升级软件包进行测试。我一有能力就会跟进。

删除正文将返回所有文档

 $params = [
        'index' => 'your_index',
    ];
    $response = $this->elasticsearch->search($params);
    dump($response);
