Codase.com - The Source Code Search Engine

Codase is a vertical search engine focused on source code. You’ve got Google, you have Yahoo and Ask, but none of these specifically addresses code, which is precisely where Codase comes in.

It searches the web for code snippets from more than half a billion lines of source code (c c++ Java, etc). What’s more, Codase reads code for what it is, i.e., not text, so results much more relevant and useful. Filters and customized search functions are readily available. Users can search functions, constants, macros, strings, etc. You’ve also got search by method call, method definition, class definition and variable among others. Results can be filtered by project and Codase will give you related keywords. You can browse APIs too.

“Codase is the leading source code search company with advanced source code understanding and xml index/search technologies. Rather than treating code as text, Codase understands programming languages, and treats code as code, the way it's supposed to be. This unique and syntax-aware approach provides the most accurate and detailed search results with fine granularity levels of controls. With Codase, one can search functions, classes, strings, constants, macros, comments and other programming language constructs.
Codase hosts huge amount of open source codes providing a much better coverage, as it covers codes usually hidden inside compressed files and source control repositories, where general search engines fail to find and index. In addition, Codase only indexes and searches high quality codes with every line of code literally validated and compiled by intelligent and powerful source code analysis engine.”

Codase is extremely targeted, and therefore very useful to programmers and coders. There’s tons of code out there, but no one engine quite manages to bring up the same sort of results as Codase, which recognizes code as code and searches accordingly.
