How do I search within a specific date range?

/date is a powerful slashtag as it allows you to search within a specific date range.  Say you want to see what bloggers wrote about a political candidate before he or she decided to run for office. You could constrain your date search to search a date range before the announcement.

Here are some examples of how to search using a specific date range:

1. Specific year: Angelina Jolie /date=2009
2. Specific month: San Francisco giants /date=march2009
3. Multiple months: Barack Obama /date=”march 2009 to may 2009”
4. Multiple years: the olympics /date=2006-2007
