Often programmers an web developers when they stuck somewhere in the code or with some errors, one use Google to find out the answer to their problem. If you aren’t satisfied with Google search ability to find the exact answer to your problem, then you may try searchco.de
Just type the function name which you want to explore and searchco.de will extract all the possible list of languages associated with that function type along with its syntax and description. If you are searching for some specific programming language then you may prefix your search like normalize java, the resultant search will now be specific to java language.
If your query is for some code snippets or debugging with your problems in existing code, then i am sure Google web search. will not likely to serve you better than Google Code Search. You can search for your code with regular expressions here. Thanks to Labnol for amazing tip.
