The tech that runs github search

Github released a nice post about the tech powering their new search

From launching our technology preview of the new and improved code search experience a year ago, to the public beta we released at GitHub Universe last November, there’s been a flurry of innovation and dramatic changes to some of the core GitHub product experiences around how we, as developers, find, read, and navigate code.

One question we hear about the new code search experience is, “How does it work?” And to complement a talk I gave at GitHub Universe, this post gives a high-level answer to that question and provides a small window into the system architecture and technical underpinnings of the product.
