I'll try to be more synthetic as possible this time. There's really nothing to say, but there's a lot to use, and maybe some time to gain!
Well, I am a Firefox user and I like the integrated search engine (the one in the upper right corner) to find stuff on Google and Wikipedia, mainly. But this morning I was wondering why I couldn't search SDN as well with this useful tool. So I went to Mozilla Firefox pages, and I found the way. It took me just a couple of hours to understand what I was supposed to do where (and I was that slow, men... 🙂

And, finally, the result is this: you can now follow the link below (please, use Firefox only) and add SDN as a search source in your Firefox search bar. Sorry but I must redirect you to my company site 'cause SDN doens't allow javascript code inside weblogs!
