Possible to specify multiple sites to search using bing?

Question

If I want to search the site: mysite.com on bing I can type:

my search terms site:mysite.com

Is there anyway to specify multiple sites to search? I've tried:

my search terms site:mysite.com,othersite.com

and

my search terms site:mysite.com site:othersite.com

but neither worked. Can it be done?

Answer 1

my search terms site:mysite.com OR site:othersite.com

Google and Blekko don’t need the OR, Bing does.
