You can query like this using curl.

curl -XGET "http://localhost:9200/application-log/eportal-engine/_search" -H 'Content-Type: application/json' -d'
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "logger.keyword": {
              "value": "org.apache.kafka.clients.NetworkClient"
            }
          }
        }
      ]
    }
  }
}'

Kibana equivalent of the above query :

GET application-log/eportal-engine/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "logger.keyword": {
              "value": "org.apache.kafka.clients.NetworkClient"
            }
          }
        }
      ]
    }
  }
}
