Ember and send Data

Why Ember have a few tutorials teaching about user interaction sending data to a server, ex. do search using Ember with two or more params. Various tutorials I see is load data first, after do a few interations when server is unnecessary after that. We know a small number off aplications work on this scenario.

I think this is the most painful when you learn Ember.

Sorry for my english.

Can you clarify your question a bit? Are you looking for help on something in particular or do you have a more broad comment on lack of more complex tutorials for Ember?

A lack of complex tutorial. That explains what deal with some stuffs, like a search or other interactions from user and after that load datas from a server e etc.
