At the official Google Code Search blog, Aleksander Fedorynski, Google Software Engineer writes about the gradual growth of Google Code Search and the latest alterations and improvements.
We've expanded our crawl to include not just complete archives and repositories, but individual code files and sample code snippets from webpages as well. Now when you search for things like [LfractalCanvas] or [nph-refresh], you'll have a better chance of finding what you want.
We've made a few ranking adjustments, such as putting class and function definitions closer to the top for a lot of searches.
Code Search is now available in domains outside the United States, from my home country of Poland, Brazil, China, France, Germany, Italy, Japan, Korea, the Netherlands, Russia, and Spain, to name a few.
