We have a scenario in which we are currently using a Queryable version of the collection as an override to another method, which "pre-filters" a search.

Given the performance gains of Builders vs Linq, We're attempting to migrate away from Linq / Queryable on calls which are made with some frequency.

We'd love to do the same equivilent with a FilterDefinition

class BaseClass<TRoot>

{ ... public IQueryable<TRoot> Queryable => Collection.AsQueryable(); }

class SomeRepository : BaseClass<SomeType>

{ public override IQueryable<SomeType> Queryable => base.Queryable.Where(st => st.Feature.In(listOfAllowedFeatures); }
