我将ID以逗号分隔的形式保存在数据库中,并将其索引到ElasticSearch。现在,我需要检索user_id是否与值匹配。

例如,它将这样保存在user_ids列的索引中(elasticsearch中的数据库类型是varchar(500),它是文本)

8938,8936,8937

$userId = 8936; // For example expecting to return that row
$whereCondition = [];
$whereCondition[]  = [
                "query_string" => [
                    "query"=> $userId,
                    "default_field" => "user_ids",
                    "default_operator" => "OR"
                ]
            ];

$searchParams = [
    'query' => [
        'bool' => [
            'must' => [
                $whereCondition
            ],
            'must_not' => [
                ['exists' => ['field' => 'deleted_at']]
            ]
        ]
    ],
    "size" => 10000
];

User::search($searchParams);

Json查询

{
    "query": {
        "bool": {
            "must": [
                [{
                    "query_string": {
                        "query": 8936,
                        "default_field": "user_ids",
                        "default_operator": "OR"
                    }
                }]
            ],
            "must_not": [
                [{
                    "exists": {
                        "field": "deleted_at"
                    }
                }]
            ]
        }
    },
    "size": 10000
}

映射详细信息

{
    "user_details_index": {
        "aliases": {},
        "mappings": {
            "test_type": {
                "properties": {
                    "created_at": {

                            }
                        }
                    }
                }

        },
        "settings": {
            "index": {
                "creation_date": "1546404165500",

                "uuid": "krpph26NTv2ykt6xE05klQ",
                "version": {
                    "created": "6020299"
                },
                "provided_name": "user_details_index"
            }
        }
    }
}

我正在尝试上述逻辑,但无法检索。有人可以帮忙吗?

由于字段user_ids的类型为text,因此默认情况下未为其指定任何分析器,它将使用standard分析器,该分析器不会将8938,8936,8937分解为{ {1}},89388936,因此ID无法匹配。

要解决此问题,建议您将ID数组存储到8937字段中,而不要存储到csv中。因此,在为您建立索引时,json输入应如下所示:

user_ids

由于用户ID是整数值,因此应在映射中进行以下更改:

{
   ...

   "user_ids": [
      8938,
      8936,
      8937
   ]

   ...
}

现在查询如下:

{
   "user_ids": {
      "type": "integer"
   }
}
