Google advanced search with in specified sites

How can I search with in two sites say for e开发者_StackOverflow社区x stackoverflow and msdn only to be searched in google advanced search?

googling for 'sharepoint site:stackoverflow.com site:microsoft.com' (without the quotes) didn't work for me. nor with a comma seperated list for site:. This is the same query that would be constructed using the Advanced Search page at google. So, I don't think it is possible, you'll have to run 2 seperate queries.

I hope this helps.
