Useful Google Search Feature: Date-Based Search to Get New URLs for the Query

Here's an advanced Google search option that didn't get much attention.Suppose you wanted to see all the new urls that Google found on internet for the query within the last 30 days.

For the query "TechDreams", I’d use a query such as http://www.google.com/search?q=TechDreams&as_qdr=d30 to find those urls (remember, “d” stands for days)

You can easily remember the parameter name as_qdr as “advanced search — query date range”.
