default spring data elasticsearch `CrudRepository` doesn't support routing

Question

Spring data CrudRepository's findById method is useful and handy to use, but in spring-data-elasticsearch, we should specify not only id but routing attribute together to find a doc in index with multiple shards.

Does it mean CrudRepository#findById is useless or even misleading(if _id is not equal to _routing) in spring-data-elasticsearch?
Is there any way to find a doc by id and routing, without construct a search request manually, in spring-data-elasticsearch?

Any suggestion would be appreciated!

Routing support is available since version 4.2 (released in April 2021) and described in the documentation.

It is supported on the ElastcisearchOperations level.

To use it in a repository you'd need to integrate it in a custom repository fragment
