Ask HN: How do I recreate the HN front page with HNSearch API?

Hello HN,

I had an interesting idea today. I am the developer of HackerNode app for HN(http://hackerno.de) and I was thinking and I would let people have their own custom news feeds with hnsearch api. (Is this a good idea?)

Now to do this I need to figure out how to create the front page first. Has anyone tackled this problem before?

I know that the sorting algorithm function for the front page is (votes - 1) / pow((item_hour_age+2), gravity) but how exactly do I put it into the boost function for thriftdb api?

Thanks Sumeru
