How to search a keyword by using google api as well as youtube api

Since Google now owns YouTube, perhaps their api includes options to include YouTube results?

Otherwise:

1. Search using Google's api.
2. Search using YouTube's api.
3. Merge the results in your application code (optional step, perhaps?)
4. Output the results in desired format.

Or was there something more specific you needed to know? ;)
