Hound: a lightning fast code search tool

Etsy's engineers recently published a code search tool (dubbed Hound) that they built to scratch their ever-growing-codebase-search itch.

The search is based on Russ Cox's Regular Expression Matching with a Trigram Index algorithm, which is served up by a Go back-end to a React front-end.

If your team has many and/or large code repositories and could benefit from a unified, fast search tool, Hound is worth a look.
