Refactor API to handle query chaining ("advanced search")

[sthiepaan]

As mentioned in #32 currently we are not able to limit the output data from the query we make (using API methods). This may result in higher cost of using that package as a resource manager.

What we could do is extend this project by refactoring the way we collect and consume the data. This could be achieved for example by creating additional methods to have different pool of the data that we handle.

Feel free to share your ideas and have an input how we could achieve this!
