我对Elasticsearch中的查询一词有疑问。我发送以下查询：

{
    "query": {
       "term": {
            "title":"Test1"
        }
    }
}

我有一个空结果：

{
    "took": 1,
    "timed_out": false,
    "_shards": {
        "total": 3,
        "successful": 3,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 0,
        "max_score": null,
        "hits": []
    }
}

但是，如果我发送以下内容：

{
    "query": {
       "term": {
            "root":true
        }
    }
}

我有：

{
    "took": 3,
    "timed_out": false,
    "_shards": {
        "total": 3,
        "successful": 3,
        "skipped": 0,
        "failed": 0
    },
    "hits": {
        "total": 3,
        "max_score": 0.2876821,
        "hits": [
            {
                "_index": "content_2018-05-30-092148",
                "_type": "topic",
                "_id": "6064f7ac-63d5-11e8-adc0-fa7ae01bbeb1",
                "_score": …
