Hi Is there a better simplified way to write this query. My logic is if collection contains customer ids and countrycodes, do the query ordey by customer id ascending. If there are no contain id in CustIDs then do the order by customer name. Is there a better way to write this query? I'm not really familiar with complex lambdas.

 var custIdResult =  (from Customer c in CustomerCollection
      where (c.CustomerID.ToLower().Contains(param.ToLower()) &&
       (countryCodeFilters.Any(item => item.Equals(c.CountryCode))) )
                                  select c).ToList();

        if (custIdResult.Count > 0)
        {
            return from Customer c in custIdResult
               where ( c.CustomerName.ToLower().Contains(param.ToLower()) &&
                 countryCodeFilters.Any(item => item.Equals(c.CountryCode))) 
               orderby c.CustomerID ascending
               select c;
        }
        else
        {
            return from Customer c in CustomerCollection
               where (c.CustomerName.ToLower().Contains(param.ToLower()) &&
                  countryCodeFilters.Any(item => item.Equals(c.CountryCode)))
               orderby c.CustomerName descending
               select c;
        }
