Is there an "error message guide" site?

I’m looking for (possibly) both an error message reference site, listing the possible error messages one can encounter and therefore what to do about it; and an error message “search engine” that researches guidelines and explanations to a specific message once typed in a search bar. The second resembling the principle upon these two site work:
