Keyword field slowdown while using IndexOrDocValues

[harshavamsi]

I was working on a query that contains a terms query on a keyword field like so

"query": {
    "bool": {
      "filter": [],
      "must_not": [
        {
          "bool": {
            "filter": [],
            "must": [],
            "must_not": [],
            "should": [
              {
                "terms": {
                  "field1": [
                    "value1"
                  ]
                }
              },
              {
                "terms": {
                  "field2": [
                    "value2"
                  ]
                }
              }
            ]
          }
        }
      ],
      "should": []
    }
  },

Since this is a terms query on the keyword field, it naturally delegates to IndexOrDocValuesQuery.
