Searching the awesome-lists on Github

Discovered the glorious awesome lists today on Github. They are available through a simple search on github, and contain curated lists of resources of all kinds on a multitude of topics. As one might expect, there is a lot of common ground between these lists, including topics and links. How could one search for a keyword through all these repositories? I have always wanted search for particular keywords or code snippets in my Emacs configuration files, or in other files in a particular location.
