在Olivere Package中替换NewBulkIndexer函数

Question

When I use elastigo in golang to save data to elasticsearch, I can use the following code

var c_es = elastigo.NewConn()
var indexer = c_es.NewBulkIndexer(50)

However, when I use olivere, the code is a bit different. If I want to make a connection, then I must use

e_olivere, err = elastic.NewClient(elastic.SetURL("my address eg : 122.000.001"))

But I don't know how to find the replacement for NewBulkIndexer(). Does anyone know what the function is?

Thanks
