Wikipedia:PHP script feature requests
Looking at mis-spelled search requests for 'Circumsision', 'Circumsicion', 'Circumsission' and 'Lamberghini', we should probably use something like Soundex or Metaphone to search for a sound-alike article if a literal search fails. Note that recent versions of PHP have a metaphone() function built in.
See http://www.zend.com/manual/function.metaphone.php for more details.
