我有一个索引与下面的Map：

"result": {
          "properties": {
            "duration": {
              "type": "float"
            },
            "endTime": {
              "type": "float"
            },
            "results": {
              "properties": {
                "offsets": {
                  "type": "long"
                },
                "output": {
                  "type": "text",
                  "fields": {
                    "keyword": {
                      "type": "keyword",
                      "ignore_above": 256
                    }
                  }
                }
              }
            },
            "startTime": {
              "type": "float"
            }
          }
        },
        "timestamp": {
          "type": "date"
        }

我搜索的数据，在与下面的请求体：

{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "timestamp": {
              "gte": "now-5d"
            }
          }
        }
      ],
      "filter": [
        {
          "terms": {
            "result.results.output": [
              "keyword 1",
              "keyword 2"
            ]
          }
        }
      ]
    }
  }
}

但我想得到的结果与一个额外的搜索时间字段，代表发现关键字列表中的每个文件。
我使用了突出显示选项，突出显示关键字在我的结果文本是2行左右，但我只想在该结果中出现的关键字。
编辑：我想有如下成果（考虑到我搜索关键字-1和关键字-2）：

我不想在搜索结果中突出显示关键字。我需要在搜索时使用相同的scripted_fields。
