vale, son una especie de notas para customizar las búsquedas... bueno, no está de más...

[quote:2b7x7arj]SearchWiki lets you customize your Google Web Search results by ranking, removing, and adding notes to them. You'll see your changes whenever you do the same searches while signed in to your Google Account, or until you decide to undo them. You can also see how other users have tailored any given search results page with their own notes and changes.[/quote:2b7x7arj]
