It’s a great initiative, but sadly error codes are ungooglable. For “GHC-39999” (with and without quotes) from this thread, it doesn’t lead me to Haskell Error Index, actually, at all (!!). Yes, I did check every google result, I did learn that GHC is a currency sign for Ghanaian cedi, but no error index in sight. It’s even worse, “Haskell Error Index” (with and without quotes) doesn’t lead me to the page also (this time I did check first 3 result pages).
Something clearly doesn’t work with that website.
