How do I access the query in code?

[gtino]

I was able to integrate the query builder and it works like a charme. The problem I have is that even if I am able to print the query using {{ options.query }} in the HTML page, I cannot access the same object when I am in code. In other words I have a controller that manages the whole page where the query builder has been inserted. This page is basically a huge form and the query builder helps me creating one of the many parameters that must be submitted. I need to be able to retrieve the query but it looks like the .query property is undefined?
