Lindocfinder is a Firefox extension. It searchs the words in the Linux documentations that we choose in the web page. It does research at MAN pages, HOWTOs ve RFCs. The only thing that you should do, is just to choose the word that you want to search and click right. Then you can choose one of the options in the menu in which page you want to search the word.
You can dowload this extension from here.
