Is it possible to extract value of data within a field in Kibana?

Hi,

I am trying to extract value of data with a field, but no luck. Please help. Many thanks in advance.

For example,

  1. I run below script to get the data
GET xx-prod-transaction-*/_search
 {
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "appName": "app1"
          }
        },
        {
          "term": {
            "Transaction-Category": "request"
          }
        }
      ]
    }
  }
}
  1. Script returns
{
  "took" : 25328,
  "timed_out" : false,
  "_shards" : {
    "total" : 250,
    "successful" : 250,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 10000,
      "relation" : "gte"
    },
    "max_score" : 9.945171,
    "hits" : [
      {
        "_index" : "xx-prod-transaction-2022.04.25",
        "_type" : "_doc",
        "_id" : "B8QnY4AB6yZ61111",
        "_score" : 9.945111,
        "_ignored" : [
          "original_message.keyword"
        ],
        "_source" : {
          "Transaction-Id" : "e821e122-1314-415e-bff4-c92445",
          "Transaction-Category" : "request",
          "Transaction-Payload" : "0436R042022042518310200000000000000000000000000000017802100000000005700157                                00055542100M3152018010120220425QD161.73     NA",
         "appName" : "app1",
          "tags" : [
            "FORMATTED",
            "TRANSACTION",
            "PROD"
          ],
          "@timestamp" : "2022-04-25T23:56:41.595Z",
          "App-Id" : "5d277dfddfd8e86e111"
        }
      }
  1. I would like to extract a value = "000555421' which is in bold from one of returned fields 'Transaction-Payload'
    "Transaction-Payload" : "0436R042022042518310200000000000000000000000000000017802100000000005700157 00055542100M3152018010120220425QD161.73 NA"

Please help. Thanks.

Hi,

Have you tried runtime fields?
