YES! We have been using hound for several years now, having all hundreds of our org repos searchable in one spot, in a LIGHTNING FAST manner has been an invaluable tool to help our various teams keep up with the legacy sprawl and effectively remove old features and all their dependencies from our sprawly systems. I even wrote a microservice that uses gitlab global hooks to keep hound up to date without polling, and a little c# config generator that runs as a cron job on our gitlab instance and redeploys hound with the newest repos included.

Hound falls short on access control front (we wrapped our instance with a saml proxy), but it's still a 'you either can search every piece of software for \'password\'' or you don't have any access at all. Having to index a specific branch instead of all of them kinda stinks too; for those two specific reasons we have been eyeing sourcegraph, esp. as the gitlab integration matures.

I can't emphasize enough how fast hound is and how pleasurable it is having a regex based code search that doesn't make me wait.
