Filter & Refine Results Using Google's Search Options Side Panel

There's an easy way to refine your Google searches, but it's subtle to see you have the option...

Just click the + next to "Show options" to see the available filters and views you can apply to your search results. Click "Hide options" to remove the options panel from view.

You can slice and dice your results to find different types of content (like videos and reviews), or results fitting a date range (the most recent results or results from a specific time period).  It even lets you filter out commercial results by choosing "fewer shopping sites".
