我有两个字段: id 以及 code . code 用作主键( _id )我也是。当我经过时 id 我可以得到结果,但如果我通过 code 一无所获。这是工作,但没有理由或改变停止工作。
elasticsearch版本:7.1
文件编号:

{
  "id": 123,
  "code": "AAAEEXXX",
  "name": "Sample name"
}

搜索查询依据 id 作品。

{
    "query": {
        "bool": {
            "must": {
                "term": {
                    "id": 123
                }
            }
        }
    }
}

结果来自 id 查询:

{
    "took": 2,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 1,
            "relation": "eq"
        },
        "max_score": 1.0,
        "hits": [
            {
                "_index": "test-index",
                "_type": "_doc",
                "_id": "AAAEEXXX",
                "_score": 1.0,
                "_source": {
                    "id": 123,
                    "code": "AAAEEXXX",
                    "name": "Sample name"
                }
            }
        ]
    }
}

但是,如果我搜索 code 不起作用。
按代码查询:

{
    "query": {
        "bool": {
            "must": {
                "term": {
                    "code": "AAAEEXXX"
                }
            }
        }
    }
}

结果来自 code 查询:

{
    "took": 2,
    "timed_out": false,
    "_shards": {
        "total": 5,
        "successful": 5,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": {
            "value": 0,
            "relation": "eq"
        },
        "max_score": null,
        "hits": []
    }
}

使用 .keyword 精确匹配的Map如下:

{
    "query": {
        "bool": {
            "must": {
                "term": {
                    "code.keyword": "AAAEEXXX"   <--
                }
            }
        }
    }
}
