how does newsblur aggregate all archived posts from a website

I have a doubt regarding how newsblur collect archived post details. An RSS feed contains limited posts. For example feed url lists around 7 TO 8 posts. But how does newsblur list almost all the posts of briancarper as I scroll down.
My question is how do you parse the website for the post archives. is there any logic or do you manually search for particular words and build from there or do you use any service for the same.
