修复 ElasticSearch 'no [query] registered for [query]'

问题：

你想在 ElasticSearch 中运行查询，但你收到类似这样的错误消息

elasticsearch_no_query_registered.txt

elasticsearch.exceptions.RequestError: RequestError(400, 'parsing_exception', 'no [query] registered for [query]')

elasticsearch.exceptions.RequestError: RequestError(400, 'parsing_exception', 'no [query] registered for [query]')

在你的查询体中，有两个 "query" 对象相互嵌套。删除外部的 "query"，只保留内部的。

示例：

不正确：

es_query_incorrect.json

{
    "query": {
        "query": {
            "match": {
                "my_field": "my_value"
            }
        }
    }
}

{
    "query": {
        "query": {
            "match": {
                "my_field": "my_value"
            }
        }
    }
}

正确：

es_query_correct.json

{
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
}

{
    "query": {
        "match": {
            "my_field": "my_value"
        }
    }
}
