Is there an official term for the automatic search that Google Instant uses once you stop typing for about 1 second? This is also used on UX.SE when searching for a user. I am looking to add this into a client application and have been searching for information on how to do it in our platform, but can't find much. My guess is that I am not using the right terminology.

Is there an official term for this type of behavior? (Not the prediction aspect, but the search results being processed without actually clicking search)

Results as you type is the term used by Google themselves (which links on to the page about autocomplete)

This SemaText page suggests a collection of terms:

  • Search AutoComplete
  • Auto-Complete
  • Auto-Suggest
  • Search suggest
  • Suggest as you type
  • Read-ahead

YUI is an example css and javascript library that has a controllable query delay that you can use to change the delay before a query is activated when the user pauses typing.

  • Sorry Roger I wasn't clear in my question, I have edited it now. I am not concerned with the predictive capabilities, but mainly the action of the search being performed without actually clicking search. Nov 14, 2011 at 13:31

  • Nope :) Closer to what I am looking for, I am going to try and see what I can find using those terms. My platform is WPF (XAML + C#). I'll see what I can find now. Nov 14, 2011 at 13:57
  • A "WPF AutoComplete TextBox" seems to be the winner. Thanks! Nov 14, 2011 at 14:02
