That's a massive fail for Google IMO. Why isn't it matching phrases for the search recommendation? Surely "to err is human" popularised by Pope [a million plus results] should be suggested before "to heir is human" (a minor computer game) [60k results].
"heir" is a much closer match for "hair" in terms of Levenshtein distance[1] (which indicates a typing error) and soundex[2] (misheard). But clearly "to err is human" should be offered as a possibility too.
