Google Code Search was a free beta product from Google which debuted in Google Labs on October 5, 2006 allowing web users to search for open-source code on the Internet. Code Search was officially shut down along with the Code Search API on January 15, 2012[1] but remains available for an unknown period of time.
Features included the ability to search using operators. These are lang:, package:, license: and file:.
The code available for searching was in various formats including tar.gz, .tar.bz2, .tar, and .zip, CVS, Subversion, git and mercurial repositories.

[edit] Regular expression engine
The site allowed the use of regular expressions in queries, which is not offered by any other search engine for code.[citation needed] This makes it resemble grep, but over the world's public code. The methodology employed combines a trigram index with a custom-built, denial-of-service resistant regular expression engine[2].
Google Code Search supported POSIX extended regular expression syntax, excluding back-references, collating elements, and collation classes.[3]
[edit] Supported languages
The list of officially supported languages was constantly changing. The following list is correct as of 31 December 2010[update]:[4]
Languages not officially supported could be searched for using the file: operator to match the common file extensions for the language.
