Facet search + Entity result

[jeremy-ritec]

Context
Currently if you want your results to be hydrated by doctrine, you would use search, but without facet results. And if you want facet results, you'd use rawSearch, but the hits would not be hydrated. So you'll need to perform two requests to get both results.

Description
Can we have a method or an option, that combines raw results from the engine with the hydrated entities from doctrine.

Basic example
$this->searchService->search($em, Entity::class,$q, $options, $fieldsToRetrieve) , where $fieldsToRetrieve is an array of strings, like ['hits','facetDistribution', 'estimatedTotalHits']

@norkunas if you are around, what do you think about this improvement? Should we tag it as good first issue?

[norkunas]

Ok for tag. But the SearchService needs some refactoring because it's tightly coupled to doctrine so my plan is to deprecate it and introduce a different one without coupling,but not sure when I'll complete this :/
