I created an index megacorp. PUT 3 documents in it through kibana console.

eg..  
PUT /megacorp/employee/2  
{  
"first\_name" : "Jane",  
"last\_name" : "Smith",  
"age" : 32,  
"about" : "I like to collect rock albums",  
"interests": ["music"]  
}

when I try to perform aggregations by passing below request through kibana console..

```
GET megacorp/employee/_search
{
  "aggs": {
    "all_interests": {
      "terms": {
        "field": "interests"
      }
    }
  }
}

```

I am getting this error response..

```
{
  "error": {
    "root_cause": [
      {
        "type": "illegal_argument_exception",
        "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [interests] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "megacorp",
        "node": "PTK-1g-dR-CV0KXVD5eMSQ",
        "reason": {
          "type": "illegal_argument_exception",
          "reason": "Fielddata is disabled on text fields by default. Set fielddata=true on [interests] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead."
        }
      }
    ]
  },
  "status": 400
}

```
