We have this code:

private IList<InfoRequest> GetBy(Func<InformationRequest, string> func, string searchby)
{
    var requests = _dc.InformationRequests
                      .Where(x => func.Invoke(x).Contains(searchby))
                      .OrderBy(y => y.RequestDate);

    return Mapper.Map<InformationRequest[], InfoRequest[]>(requests.ToArray());
}

It continues to throw the no supported translation to SQL error. Any ideas on the problem or how to resolve it?
