    Description

      Add support for LINQ queries like:

      var query1 = from c in collection.AsQueryable<C>()
      		 
                   where c.A.Any(a => (a % 2) == 0 && a > 2)
      		 
                   select c;

      This example assumes c.A is an array of ints and is looking for documents where c.A contains an even number greater than 2. It requires use of $elemMatch, but there is some concern about use of $elemMatch when the array values are not embedded documents.

      In any case, full support for mapping arbitrary C# predicates on array elements requires robust $elemMatch support in the server, including support for scalar or document values as well as $and and $or.
