```auto
AggregationBuilder group = AggregationBuilders.terms("agg1")
                .field("requestId").subAggregation(AggregationBuilders
                        .max("agg2").field("startTime"));

```

The value of field requestId is split and the result is wrong. And I put mapping like:

```auto
client.admin().indices().preparePutMapping(indexName)
                .setType(type)
                .setSource("{\n" +
                        " \"" + type + "\":{\n" +
                        " \"properties\": {\n" +
                        " \"requestId\": {\n" +
                        " \"type\": \"text\",\n" +
                        " \"fielddata\": true,\n" +
                        " \"index\": \"not_analyzed\"\n" +
                        " }\n" +
                        " }\n" +
                        " }\n" +
                        "}")
                .get();

```

I can't get the right result.

Try `"type": "keyword"` instead.
