By adding the &_as_qdr=d1 variable to your query, you're telling Google to only bring back pages discovered in the past 1 day (d1). You can simply type this query in the URL after you've completed your search, or if you like a GUI approach, you can use the Advanced Search function on the Google website. It looks like this:
You can also use this technique to find which pages Google has indexed on your website within the past 30 days. This can be helpful as part of your overall SEO/SEM strategy, especially if you're publishing time-sensitive content, such as technology news, that you don't think Google is indexing in a timely manner.
