Allow setting returned fields in search_request.xml

[aapokiiso]

Summary (*)

It's not possible to customize fields returned by search engines (for example Elasticsearch) in search_request.xml.

Examples (*)

In the case of Elasticsearch, Magento\Elasticsearch\SearchAdapter\Query\Builder forces the returned fields to be ['_id', '_score']. This is OK in the case of product search, because you can fetch the remaining data through the product repository using the returned product IDs. But in simpler search cases, it would be nice to return the fields directly from the search index.

Proposed solution

I could provide a PR for this, but is there an explicit reason this is not possible at the moment? Maybe some incompatibility issue between search engines, which prevents this being part of the search_request.xml abstraction?
