The specified entity does not exist ms crm 2011 rest point call

i was using a REST call from javascript for an entity, suppose new_test
if i use the url(query) as the entity name with out Set with the entity, then it will give error "The specified entity does not exist"."/XRMServices/2011/OrganizationData.svc/" +  "new_patient?$top=1&$filter=new_Name eq '" + "test" + "'";
serverUrl +

so make it
serverUrl + "/XRMServices/2011/OrganizationData.svc/" +  "new_patientSet?$top=1&$filter=new_Name eq '" + "test" + "'";
Also make sure that attribute names ex; new_name is as new_Name, if its as new_Name, n is caps letter, else it will show the speficied column is not present.

thanks,
