Hi all.

I have a difficulty, described in

I have some real index data that looks like this: "\_source": { "price": 10000, "params\_model": "Дверь задняя правая Honda CR-V", "categories": [ { "id": 3, "shop\_category\_id": "3", "name": "Кузов наружные элементы", "level": 1 }, { "id": 342, "shop\_category\_id": "62", "name": "Дверь …

I suppose that the reason is in mapping differences between the index created in my test and the real index in the real elasticsearch installation.

I've found the way. It is the use of CreateIndexRequestBuilder.addMapping(). The question about the index mapping in the integration test is closed.
