Filtering by array property

[echernyavsky]

Let say I have the following structure:

public class Company
{
     [Sieve(CanFilter=true, CanSort=true)]
     public IEnumerable<long> CustomerIds { get;set; }
}

How can I filter CustomerIds on contains? As far as I get the default @= works only with strings.
Actually need something like:
?filters=customerIds@=3|18

Thanks in advance!

Possible duplicate of #101. Meanwhile, a Custom Filter Method should do. By the way, @= operator is engineered to work with strings. == operator with OR logic would do also.
