if I insert this field in this order: `"name_of_field": {"first":1,"second":2,"third":3}` will it always save in the same order as I inserted ? Based on my test, inserting multiple objects like that can make it save it different order, like: `"name_of_field": {"third":3,"first":1,"second":2}` ---

Elasticsearch does not change the document but JSON serialisation and deserialisation does generally not guarantee that order is preserved. ---

Is there any way I could enforce an order on a particular hash field ? ---

To do so you would need to control how your documents are serialised and deserialised which means e.g. not using scripted updates. Which client(s) are you using? ---

Ruby Elasticsearch gem: [https://github.com/elastic/elasticsearch-ruby](https://github.com/elastic/elasticsearch-ruby) Do you want me to send the update query here ? ---

I will update recommended not relying on the order as it will be more resilient given that ordering is generally not guaranteed. ---

Alright then, so the best will probably be to put it under an array, like: `"name_of_field": [{"first":1},{"second":2},{"third":3}]` ---

That sounds like a bad idea. Why do you feel you need to preserve order?? ---

This object will be sent through an API that will send to the browser and it needs to be displayed in a certain order ---

Sort it in the browser? ---
