How I hacked HN Search at the fHACKtory hackathon last weekend

Same, searching HN is no "hack" unless it was done in a novel or interesting way. This might even be a cool hack, but I dont know!

I'll write a blog post about it in a few days. Thx for the feedback

If by "hack" you mean "break/exploit/...", I totally agree. But hackatons are more codefests, calling "hack" every piece of code written in a short amount of time. That's only my 4-hours project implementing a custom crawler, work-arounding black-listing, and indexing it with Algolia. BTW, I'll write a blog post explaining the underlying ranking algorithm, which is the real point.

Since the crawl started 3 days ago only, assuming that I fetch only the first 10 pages, lots of terms are not yet in the indexed corpus. But querying "fracking", you can at least see the typo-tolerant instant search in action ;)
