Bool查询子字段和父字段

Question

刚开始玩Elasticsearch。 我试图通过查询子字段和父字段来搜索某些子文档。

{
    "query": {
        "bool": {
            "must": [
                {
                    "has_child": {
                        "type": "mychildtype",
                        "query": {
                            "match": {
                                "child_field": "value1"
                            }
                        }
                    }
                },
                {
                    "parent_field": "value2"
                }
            ]
        }
    },
    "fields": [
        "_type",
        "_id",
        "parent_field1",
        "parent_field2"
    ]
}

我收到错误：

{
  "error" : "SearchPhaseExecutionException[Failed to execute phase [query_fetch], all shards failed; shardFailures {[PfjRtoQKRZeIxkokAo_vmA][*INDEX_NAME*][0]: SearchParseException[[*INDEX_NAME*][0]: from[-1],size[-1]: Parse Failure [Failed to parse source [*ESCAPED QUERY*]; nested: QueryParsingException[[*INDEX_NAME*] [_na] query malformed, no field after start_object]; }]",
  "status" : 400
}

我在这里做错了什么？

Answer 1

我错过了一个“匹配”：{}围绕我的父字段标准。
