you are right that it is a bad practice, and I have indicated to modify the JSON in the way as you have said, with unique fields. But the above documents are created and I am looking into how to fix it with Elasticsearch.  
I have looked at the query\_string with range function:

Do you think this function can help me?  
Thanks for your answers
