What does self.$query(self, self.callback('index')); do?

[blaasvaer]

Following your recommendations I'm trawling through some of the source code for some of your apps. And in this quest I've come upon this in a controller (for the Blog Engine):

self.$query(self, self.callback('index'));

So, in order to try to understand what is going on here, I went into the model to see if I could somehow figure out what this 'index' string was doing in this context. Now, to my own surprise I couldn't figure it out from simply reading the code ...

So, what is the string 'index' doing in this context?

I ask this because the code is complete without comments. Of course apart from comments like these:

        // Refreshes cache
        F.cache.remove('partial-menu');
        F.cache.remove('partial-tags');
        F.cache.remove('partial-latest');
        F.cache.remove('homepage');

"index" is meant to be the name of the index view which is located at {blog_engine_root}/themes/default/views/index.html . This is clearly documented in the docs under the FrameworkController section

But VERY hard to pick up from reading the source code from an app. And even though having read the docs I didn't make that connection ... things are to wide apart.

And you have to admit that:

self.$query(self, self.callback('index'));

Is NOT very self explanatory.
