Google now allows the use of the tilde sign (~) before a search term
to
expand the search to include synonyms of the term. They give the
example
of searching for '~food ~facts' to also find information on nutrition
and cooking(http://www.google.com/help/refinesearch.html). 

As I understand it this should EXPAND a search, thus retrieving more
hits. Has anyone used it, and does anyone see the logic behind a
search
for '~odor' retrieving LESS hits than a search for 'odor'?
