Google can find lots of different things, but at this writing, it can't find
special characters in its search results. That's a shame, because special
characters can come in handy. The tilde (~), for example, denotes personal
web pages.

This hack takes a query from a form, pulls results from Google, and filters
the results for the presence of several different special characters in the
URL, including the tilde.
