Is your feature request related to a problem? Please describe.
Because we want to prevent issues when restoring a database backup and keeping the same searchkick index. We want to include a tenant id into the search_document_id. Currently, when using search with the load option, this will result in problems. Since searchkick can't find the accompanying record.

Describe the solution you'd like
Add an optional way to find the record in the case the search_id is overridden. Such as a "find_by_search_document_id" method or similar.
