I hacked HNSearch in the formal way in this article: http://blog.databigbang.com/ideas-and-execution-magic-chart/ python code is also here: https://gist.github.com/srw/1360455

Basically I could search beyond the HNSearch limits. The article is from 2011 so I don't know if it's working now.

Nice post, I'll release the rails4-based source code before the end of the week. Hopefully with a blog post explaining the underlying ranking algorithm.
