The lower-level collection, resolved from dependency injection or opened through IDocumentStore. In addition to the operations above it offers:

Member	Purpose
`WhereAsync`	Query with a filter string, LINQ or a JSON filter; the result carries a query Explanation.

INamedNetlyDBCollectionProvider<T> - resolve named collections of one type.
