While I generally don't have much love for Oracle, this is a thing they do well. All the messages are numbered like ORA-123456 and are dead easy to google without mixing in any other results. You also sometimes get an error message containing relevant parameters. Microsoft does acceptably wel with their 0x80071234, but no parameters, messages like 'installer failed', and googling them gives 10 zillion sites with crap results.
