elasticsearch - OrchardCore match_phrase不返回结果

Question

我有以下查询

{
  "from": 0, "size": 10000,
  "query": { "match_phrase": {"Practitioner.DoctorList": "peter goh"} },
}

它不会返回任何结果。
但以下内容:

{
  "from": 0, "size": 10000,
  "query": { "match": {"Practitioner.DoctorList": "peter goh"} },
}

返回具有“peter goh”，“peter”和“goh”的内容。match_phrase为什么不返回任何内容？因为我只希望结果与“peth goh”匹配。

由于尚未添加任何样本数据和索引映射，(考虑到Practitioner为nested类型)
引用match_phrase查询，以获取详细信息
添加带有索引数据，映射和搜索查询的工作示例。
索引映射:

{
  "mappings": {
    "properties": {
      "Practitioner": {
        "type": "nested" 
      }
    }
  }
}

索引数据:

{
    "Practitioner": [
        {
            "DoctorList": "goh"
        },
        {
            "DoctorList": "peter goh"
        },
        {
            "DoctorList": "peter"
        }
    ]
}

搜索查询:

    {
  "query": {
    "nested": {
      "path": "Practitioner",
      "query": {
        "match_phrase": {
          "Practitioner.DoctorList": "peter goh"
        }
      },
      "inner_hits":{}
    }
  }
}

搜索结果:

"hits": [
                {
                  "_index": "fd_cb3",
                  "_type": "_doc",
                  "_id": "1",
                  "_nested": {
                    "field": "Practitioner",
                    "offset": 1
                  },
                  "_score": 0.78038335,
                  "_source": {
                    "DoctorList": "peter goh"
                  }
                }
              ]
