Google Search: **/*

Doesn't seem limited to " * * / * ", but rather any search within asterixis that contain non-letter characters. E.g., "* '* ", "* @* ", ...

(Also, I'm not sure how to escape asterixis in HN comments other than adding a space after them.)

Thought this was a little odd. For me it just shows listings for local businesses. When I'm on a VPN, though, the search does not match any documents.
