Google abandoned the field
When I was a child, I used Google to search the internet for code. (Code repositories used to live in files on http servers) But as Google gradually improved their algorithm, they excluded punctuation from their index. You can do 'exact match', but the information simply isn't there anymore. It's actually been years since I tried to do a code search using Google -- something I used to do frequently.
