Would you (or anyone else) be willing to write up a page for that site to document what Amazon's internal code search is like (from publicly available sources)?

Im not sure much is public info. I'm not there anymore but perhaps someone who is can.

Its called GitFarm and had a web UI where you could search with a few different operators, like exact word, path, file extension. They kinda half implemented searching by class name just for Java too. Another thing, you couldn't add a NOT, or exclude certain filepaths, which was annoying especially when ppl would accidentally commit node_modules. Overall, it wasn't too bad buy feels like it had kinda stagnated recently (KTLO).
