Hi,

While writing a snippet where I have to query a model with loads of records in it (800+) I felt the urge to use model.sync() instead of model.updateData() because of the load time. As far as I can tell model.sync() is basically the “get more” version of the multiple actions. 

I know model.sync() is a prototype method and not documented by any means.
Although there is a bug in it and I really would like to have it as an official function

Cheers
