I came across this one yesterday when I was looking for more information about something mentioned on HN:
Search: carmack +zfail gpl
Date: 2011-11-02
Result: Bad autocorrect; Plus operator broke
"""
Showing results for carmack fail gpl
Search instead for carmack zfail gpl
"""
Because the plus operator is broken my final search ended up being `carmack "z-fail" OR "zfail" gpl` because different sources included or excluded the dash. Note that I think it's good that quotes are still exact and they shouldn't do the synonym search, but this is something the plus operator would have worked on, if I remember correctly.
