Check out Google's Search Options function, a collection of new tools to filter searches:
- by type: reviews, videos, images, etc.
- by time: most recent, a week ago, etc.
- related searches to expand a query including a Wonder Wheel graphic
Google are also previewing a new tool called Google Squared. GS doesn't find webpages about your topic; instead it automatically fetches and organizes facts from across the Internet. Available to users at the end of May on Google Labs.
