What does HackerNews think of dcs?

source code of Debian Code Search (codesearch.debian.net)

Language: Go

See also https://codesearch.debian.net/ - https://github.com/Debian/dcs for a similar project that may fit your needs better. I've not compared them both, but I use dcs frequently
For another example of a code search service written in Go, see the software powering http://codesearch.debian.net
