Hi lantian FU,

The getGeneratedIds() does exactly the same it's description says: "Get a list of document ids generated in the server for the documents added by collection.add()".

For example:

// document with assigned _id
String json1 = "{'_id': 'Id#1', 'name': 'assignedId'}".replaceAll("'", "\"");
// document without assigned _id
String json2 = "{'name': 'autoId'}".replaceAll("'", "\"");
// add one document with assigned _id and two documents without _id
res = this.collection.add(json2).add(json1).add(json2).execute();

List<String> ids = res.getGeneratedIds();
//gives ids == [00005b6408fc000000000000000b, 00005b6408fc000000000000000c]

I.e. _only_ generated ids are returned by this method.
