An Updated version is now available at Sublime Plugins – Search Anywhere
This plugin is an improvement over Sublime Text 2 Search Stack Overflow where the user can now choose which search engine to use by default and per file type. This means that you could have all your .js files search on Stack Overflow, while all your .php files search on php.net and any other search on Google, for example.
All the commands are available through a simple set of menus in the Tools section or with the right click of the mouse. They are also all listed under Search Anywhere in the command palette.
For now, the supported search engines are Google, Stack Overflow, PHP.net, Bing and Yahoo. In the next version I will add a command to “suggest” a new search engine to be added.
Please do not hesitate to contact me with any question or feedback!
