Well as useful as the Google code search is Google simply have not taken the ActionScript community into consideration. U can not simply search for actionscript + a key word which u could do with other languages. There is still hope for all the Google junky flash developers. Cause u can search for file types ‘.as’ basically. I put a request in to recognize ActionScript as a language.
see google’s programmers search engine http://devshots.com
Devshots returns Google search results, but emphasize on programming related sites and resources. So the search result will be smart and accurate.
