Google has stop paying attention to it’s own search commands. I can +search term in my search and it will still bring up the same results it brought up in the previous search that made me include the + in the first place, even when I know results with that term exist.

Also if it decides you’ve typo’d, it often no longer gives you the option to search for the exact thing you typed. It used to say “did you mean __________?” and you could click a link to search for the exact word it thins you mistyped. It now often doesn’t give you that option anymore.
