[QUESTION] Generic searching on ILiteQueryable<T>

[ssteiner]

I would like to perform a generic search like this:

var table = context.GetCollection<T>();
var query = table.Query();
if (typeof(INamedItem).IsAssignableFrom(typeof(T)))
{
    var myItems = query as ILiteQueryable<INamedItems>;
    // now run a filter on the ILiteQueryable<INamedItem>
    query = myItems as ILiteQueryable<T>;
}

But, myItems is always null. I've been using the same approach with EFCore (where I work with IQueryable<T> instead of ILiteQueryable<T>) - what do I need to do do get a properly typed ILiteQueryable so I can use Linq syntax to run queries rather than to have to write BSonExpressions?
