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. Features included the ability to search using operators, namely 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.
Google Code Search covered many open-source projects, and as such is different from the "Code Search for Google Open source projects" that was released afterwards.[1][2]
In March 2010, the code of RE2, the regular expression engine used in Google Code Search, was made open source.[4]
Google Code Search supported POSIX extended regular expression syntax, excluding back-references, collating elements, and collation classes.
Languages not officially supported could be searched for using the file: operator to match the common file extensions for the language.
Discontinuationedit
In October 2011, Google announced that Code Search was to be shut down along with the Code Search API.[5] The service remained online until March 2013,[6] and it now returns a 404.
In January 2012, Russ Cox published an overview of history and the technical aspects of the tool, and open-sourced a basic implementation of a similar functionality as a set of standalone programs that can run fast indexed regular expression searches over local code.[7]
