```

When I do a search on the same,

```auto
GET blogs_fixed2/_search
{
  "size": 1,
  "_source": false,
  "fields": [
    "content"
  ]
}

```

I get the below result, which doesn't have the analyser applied to it

```auto
{
  "took": 1,
  "timed_out": false,
  "_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": {
      "value": 4666,
      "relation": "eq"
    },
    "max_score": 1,
    "hits": [
      {
        "_index": "blogs_fixed2",
        "_id": "aieZmIcBbskhfV7CHLs1",
        "_score": 1,
        "fields": {
          "content": [

        }
      }
    ]
  }
}

```

I believe the analyser should be applied by default r8. And also, if I do a terms aggregation on **content** field, then it should bucket the different tokens in the field.

Analyzers do not change the source document, just how this content is parsed and indexed.

You can see this if you use the [analyze API](https://www.elastic.co/guide/en/elasticsearch/reference/8.7/indices-analyze.html).

```auto

```

Using the above, I am trying to display the indexed value of content.
