ElasticSearch Highlighting在使用Ngram Analyzer对索引进行匹配查询时失败

我已经在索引和自定义_all的所有字段中创建了一个带有ngram分析器的索引。索引几个文档之后，我试图查询索引以获得类似功能的建议。

查询的输出会返回结果，但不会突出显示。

分析仪设置： 

"analysis": {
  "analyzer": {
    "my_edgegram_analyzer": {
      "filter": [
        "lowercase"
      ],
      "tokenizer": "my_edge_tokenizer"
    }
  },
  "tokenizer": {
    "my_edge_tokenizer": {
      "token_chars": [
        "letter",
        "digit",
        "punctuation",
        "symbol"
      ],
      "min_gram": "3",
      "type": "ngram",
      "max_gram": "26"
    }
  }
}

映射：

    "mappings": {
      "a": {
        "_all": {
          "enabled": false

              }
            }
          }
        ],
        "properties": {

          }
        }
      }
    }
  }
}

文件：

http://localhost:9200/st1/a/1

{"imp_server_name":"abc2-5-ajm9.my.test.com","imp_server_id":"vrock2-us"}

查询： 

{
    "query": {
        "match": {
           "catch_all": {
            "query":"test",
            "analyzer": "keyword"
           }
        }

    },

        "_id": "1",
        "_score": 0.16292635,
        "_source": {
          "imp_server_name": "abc1-4-jam9.my.test.com",
          "imp_server_id": "vrock2-us"
        },
        "highlight": {
          "imp_server_name": [
            "abc1-4-jam9.my.test.com"
          ],
          "catch_all": [
            "abc1-4-jam9.my.test.com"
          ]
        }
      }
    ]
  }
}

如何在上述场景中突出显示工作。以下是预期产量：

预期输出： 

"highlight": {
  "imp_server_name": [
    "abc2-5-ajm9.my.<b>test</b>.com"
  ],
  "catch_all": [
    "abc2-5-ajm9.my.<b>test</b>.com"
  ]
}

我可以通过在架构中设置term_vector来获得结果。
