Hi Team,

I am new to elastic search/kibana.  
I have a field _ **"exceptions"** _. I want to make this field as aggregatable, so that I can use this field for my visualization dashboard to fetch the count of exceptions. Kindly help me to fix this.

Please find the mapping here:

```auto
{
  "rs-glsss" : {
    "mappings" : {
      "properties" : {
        "@timestamp" : {
          "type" : "date"
        },
        "corelationId" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "exceptions" : {
          "type" : "text",
          "fields" : {
            "keyword" : {
              "type" : "keyword",
              "ignore_above" : 256
            }
          }
        },
        "host" : {
          "type" : "text",
          "fields" : {
            "keyword" : {

```

Need help!

That field has two mappings. The keyword subfield can be aggregated and has the same data.

I have given the solution. Try it. I would also recommend you read [this part of the docs](https://www.elastic.co/guide/en/elasticsearch/reference/7.11/multi-fields.html).

To answer your question;

> [@Suvarna\_S](#):

> I have a field _ **"exceptions"** _ . I want to make this field as aggregatable,

You need to change the mapping and use a `keyword` type.

The solution depends on whether you want search capability for the `exceptions` fields as well as aggregation capability.

If you want to use Elasticsearch's search capability then you should do as @Christian_Dahlqvist has said. Use `exceptions.keyword` as your aggregation field. As stated, this has the same data but has not been put through elastic's field analyzers and been tokenized.

This does not require a change to your mapping or a reindex of the data.  
If you can change the mapping and re-index and will only want to use the value of the field as a whole, not in parts (i.e. full string matching) then changing the mapping for the field to a `keyword` type, as @dadoonet suggests, will have the same effect and aggregations can then be done on the `exceptions` field natively.

To be clear, there is no difference in the result of the aggregation between using `exceptions.keyword` and changing the field to type `keyword` and using `exceptions` in your aggregations, but it will change what else you can do with the field.
