    public interface CqResults<E>
extends SelectResults<E>
    Represents the results of a CQ query that is executed using CqQuery.executeWithInitialResults() The result will contain the instances of Struct having key and value of the region entry that satisfy the CQ query condition. 
     ClientCache cache = ...
 QueryService queryService = PoolManager.find("client").getQueryService();
 CqAttributesFactory cqAf = new CqAttributesFactory();
 CqAttributes cqa = cqAf.create();

 String cqQueryStr = "SELECT * FROM /root/employees " +
   "WHERE salary > 50000";

 CqQuery cq = queryService.newCq("MyCq", cqQueryStr, cqa);
 CqResults results = cq.executeWithInitialResults();

 for (Object o : results.asList()) {
   Struct s = (Struct)o;
