Hi ,  
Can any one provide sample code to insertorupdate document into ES index. I tried below code but it is creating single document (i have 300 rows in sql). I want to have single method to insert or update as I am not sure if the document is created or updated at source. Please help.  
var descriptor = new BulkDescriptor();  
descriptor.Index(ESIConfig.DataSync.CatalogName);  
foreach (var item in data)  
{  
descriptor.Update\<Dictionary\<string, object\>\>(u =\> u.Id(ESIConfig.DataSync.UniqueIDColumn).Doc(item).DocAsUpsert());  
}  
var res = Client.Bulk(d =\> descriptor);
