If you want to view Google search results in a specific time frame you can use additional operators to filter Google searches by date or time.

When you do a normal search using the word ‘grapes’, the URL bar usually looks like this:
http://www.google.com/search?hl=en&q=grapes

To filter results you can add the command &as_qdr=d at the end of the URL. You can change d (days) to w (weeks) or y (years), and adding a number at the end indicates how far back in time the search results should show.

Here are example usage:

http://www.google.com/search?hl=en&q=grapes&as_qdr=d
shows results over the past 24 hours for grapes

http://www.google.com/search?hl=en&q=grapes&as_qdr=d3
shows results over the past 3 days for grapes

http://www.google.com/search?hl=en&q=grapes&as_qdr=w5
shows results over the past 5 weeks for grapes

http://www.google.com/search?hl=en&q=grapes&as_qdr=y2
shows results over the past 2 years for grapes
