As far as I can read the code

> <https://github.com/elastic/elasticsearch/blob/6.x/server/src/main/java/org/elasticsearch/action/search/SearchResponse.java#L245-L249>

It looks like `innerFromXContent` is also parsing the aggs part.

> <https://github.com/elastic/elasticsearch/blob/6.x/server/src/main/java/org/elasticsearch/action/search/SearchResponse.java#L288-L289>

This is calling:

> <https://github.com/elastic/elasticsearch/blob/6.x/server/src/main/java/org/elasticsearch/search/aggregations/Aggregations.java#L134-L152>

Behind the scene this needs to know what kind of aggregation you asked for, what is the java type to use. The magic is happening here:

> <https://github.com/elastic/elasticsearch/blob/6.x/server/src/main/java/org/elasticsearch/common/xcontent/XContentParserUtils.java#L122-L161>

So you need to add a prefix like `terms#` if you are getting back a terms aggregation.

`terms#foo` as the javadoc example says.

I hope this can help.
