"other" just means it's not one of the other simple types in the enum. The
Elasticsearch Java API returns the search result as a Map<String, Object> type
which is also the return type of the controller so it's up to Jackson to
serialize it. We are not doing anything special to map values to types when
returning search results. So far I haven't seen Jackson have any problems with
the types being returned. From what I can tell Elasticsearch mostly sticks to
simple types for the values.
