Hello,  
I am trying to get all the values for a filed with count using Aggregation Here is my code

```auto
Query searchQuery = new NativeSearchQueryBuilder()
                   .withQuery(QueryBuilders.matchAllQuery())
                   .addAggregation(AggregationBuilders.terms("ProgramNames").field("measurementName").order(BucketOrder.key(true)))
                   .build();
           
           SearchHits<Measurement> meas = elasticsearchTemplate.search(searchQuery, Measurement.class);

```

Hey,

I haven't dug too deep in the code. I assume you ran `bucket.getKeyAsString()` before looking in the debug output? I just want to make sure, that there is no lazy initialization happening, as the `BytesRef` above named `key` seems not to be null.

Apart from that, this looks perfectly fine from a code perspective, I do have pretty much the same code in my own app.
