This code fixes this problem.

PUT megacorp/_mapping/employee
{
   "employee": {
      "properties": {
        "interests": {
          "type": "text",
          "fielddata": true
        }
      }
   }
}

So this code will run thereafter:

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