Hey Peter, can you tell me, where your problem with the above approach actually is? You feed a number of key/value pairs into elasticsearch, each key and each value is evaluated by its type and then put into the mapping, as each key becomes an own field in elasticsearch, which can be searched for. Wondering why this is a problem for you? Or why do you want to avoid that?
Also, where and how do you want to change the mapping to? I am a bit confused what and why you are expecting to be different than it actually is. Maybe you should not think in java data structures but rather in JSON, which is being indexed and needs to create a mapping in order to be able to search for it. Happy to help, if I understand what you are trying to do. Please elaborate. --Alex On Mon, Jan 13, 2014 at 11:15 AM, Oliver B.
