Elasticsearch is not a schemaless datastore but rather creates the schema on write as data is discovered. Every field must have a single mapping, which means it typically can not handle completely dynamic data. While all fields can be stored as mapped as strings (which limit what you can do with them) A field can not be an object (have sub fields) and in another place hold a value.
