Where is the link to the search page? When I go to github.com and it displays my dashboard, I can't find anything resembling a link to the search page. There's the command bar, but it doesn't seem to provide code search unless you click the advanced search link. I love the new features Github has developed over time, but if it's a pain to find the feature, it's not going to see a lot of use.
https://github.com/search and https://github.com/search/advanced respectively.
But you can just use the dashboard search.
