The search-as-you-type feature in v7 is great, but it has an annoying flaw: it is not throttled. It searches immediately every time a key is pressed.

When typing even moderately fast, this causes problems, as you type faster than the searches can complete - especially given that a search for one or two letters will usually take a bit longer, as more results are returned.

Thus, when searching for "test", when I finish typing, I will first get the results for "test". Then, it will append search results for "t" and perhaps "te" to the result list ''after'' I have finished typing. This should not happen.

Instead, searching should be throttled, so that a search request is only sent to the server after a short delay of 1-200 ms, so as to ensure that the user has (temporarily) finished typing. This will also reduce server load.

In AngularJS 1.3, this would be the perfect solution: https://docs.angularjs.org/api/ng/directive/ngModelOptions But as Umbraco 7.1 only uses AngularJS 1.1 as far as I can tell, we'll probably need something less elegant...

Search uses _.debounce so it is throttled, increased the timer from 100ms to 300ms tho
