CC Search at http://search.creativecommons.org (also accessible via Firefox) simply "frames" CC-enabled search engines.

To accomplish this, candidate search engines need to support the following query components in GET URLs:

• keyword
• restriction to only CC-licensed or PD results
  • restriction to only results that permit commercial use
  • restriction to only results that permit derivative works

Typically, these will map to four URLs, each with an arbitary keyword parameter.

Technical implementation no guarantee of inclusion

Typically only the "best" search for a category will be included directly in the http://search.creativecommons.org interface, entirely at the discretion of Creative Commons.
