The solution is to create a text field with a keyword sub-field so that you can do both, search text and aggregate values:

Your field mapping should look like this:

{
    "my_field": {
       "type": "text",
       "fields": {
           "keyword": {
               "type": "keyword"
           }
       }
    }
}

Using the above mapping, you can search on the my_field field and aggregate and my_field.keyword.
