Google Instant, Google search-as-you-type

Google Instant, Google Search predict what query you're typing & display the results for that query in real-time. Search as you type. It�s a simple and straightforward idea�people can get results as they type their queries. Imagining the future of search, the idea of being able to search for partial queries or provide some interactive feedback while searching has come up more than a few times.

Google search-as-you-type demos were thought-provoking�fun, fast and interactive but fundamentally flawed. Why? Because user don�t really want search-as-you-type (no one wants search results for [bike h] in the process of searching for [bike helmets]). User really want search-before-you-type�that is, you want results for the most likely search given what you have already typed.

As you can imagine, searching even before someone types isn�t easy�which is why Google unveiling Google Instant. Google Instant is search-before-you-type. Instant takes what you have typed already, predicts the most likely completion and streams results in real-time for those predictions�yielding a smarter and faster search that is interactive, predictive and powerful.

* Dynamic Results - Google dynamically displays relevant search results as you type so you can quickly interact and click through to the web content you need.
* Predictions - One of the key technologies in Google Instant is that we predict the rest of your query (in light gray text) before you finish typing. See what you need? Stop typing, look down and find what you�re looking for.
* Scroll to search - Scroll through predictions and see results instantly for each as you arrow down.


Google Instant features:



To bring Google Instant to life, Google needed a host of new technologies including new caching systems, the ability to adaptively control the rate at which Google show results pages and an optimization of page-rendering JavaScript to help web browsers keep up with the rest of the system. In the end, Google needed to produce a system that was able to scale while searching as fast as people can type and think�all while maintaining the relevance and simplicity people expect from Google.

The user benefits of Google Instant are many�but the primary one is time saved. Google testing has shown that Google Instant saves the average searcher two to five seconds per search. That may not seem like a lot at first, but it adds up. With Google Instant, estimate that it will save users 11 hours with each passing second!

As part of current rollout, Google Instant will become the core search experience on Google.com for Chrome, Firefox, Safari and IE 8. Google also be offering Google Instant to users in France, Germany, Italy, Russia, Spain and the U.K. who are signed in and have Instant-capable browsers. Over the coming weeks and months, they�ll work to roll out Google Instant to all geographies and platforms.
