Instant search, results showing directly

[Snookerman]

I have seen many websites with a search feature that displays the results in real time, without having to hit return. I have tried to search for this but since I have no clue of what it's called I haven't found anything. Does anyone know how to do this or at least what it's called? Here is an example, it's in Swedish (the best example of this I've seen), just go to the search box, SÖK, and type anything, like DVD player, and you will see the results show bellow:

I believe its done using AJAX (Asynchronous JavaScript And XML).

Thanks! Unfortunately I don't know much AJAX. Does anyone know how to do this?

Do a Google search for "live search". You'll get tons of resources. There are many ways to do this. Most depend on how you plan to supply the information to the search box.

I personally use jQuery LiveSearch (http://ejohn.org/blog/jquery-livesearch/) when I need to do something like this.

Thanks! I will take a look at that

The problem was I didn't even know what it was called, I had searched for live search but since most of the top results were related to Microsoft's Live search I though it should be called something else.
