Counting Terms In Text Field

[Musab_Dogan]

The fieldata disabled by default. You should enable it to use text field type in the aggregation or Kibana visualization.

Here is an example for you.

#push example data
PUT collection_test2/_doc/1
{"text_field":"word1 word2 word3"}

PUT collection_test2/_doc/2
{"text_field":"word2 word2 word3 word4"}

#enable the fielddata to true
PUT collection_test2/_mapping
{
  "properties": {
    "text_field": { 
      "type":     "text",
      "fielddata": true
    }
  }
}

#Create visualization or search your text field type data
GET collection_test2/_search
{
  "size": 0,
  "aggs": {
    "NAME": {
      "terms": {
        "field": "text_field"
      }
    }
  }
}

Note: You should update the Kibana data view after update the index mapping and refresh the browser => Stack Management => Data views => collection_test3 => refresh (there is a button for that)

Note2: The result will show the number of docs that contains per wordX.
