Description

Today the API returns a List which suggests there's an ordering going on. This may be confusing if one uses FacetsAccumulator.create which results in a MultiFacetsAccumulator, and then the order of the results does not correspond to the order of the requests.

Rather than trying to enforce ordering, a simple mapping may be better even for consuming apps since they will be able to easily lookup desired results.
