Google Suggest, a feature that offers auto-completed phrases when composing a search query, has become the latest product to graduate from the company's testing grounds. Already present in a plethora of Google's other products, Google Suggest now helps you figure out that search term on the tip of your tongue with help from Google.com.

Launched as one of Google's famous "20 percent projects" back in 2004, Google Suggest debuted with its own specific URL and an inconspicuous search box. The idea behind the feature is that Google's search box can help you search more efficiently by filling in blanks, completing phrases, or correcting spelling before you ever hit the Return key. Apparently Google noticed that that the know-it-all "Did you mean?" suggestion link that appears above search results from misspelled queries was getting on our collective nerves.

The strange thing about Google Suggest's journey to the One Searchbox to Rule Them All is that many products from Google and others were quick to adopt it. Google Toolbar, Maps, Web Search (in select countries), Google's iPhone and BlackBerry apps, and YouTube all adopted Google Suggest's type-ahead advantages some time ago. Even Firefox's search box and countless other products from affiliates and competitors all began using it.

Judging from today's announcement on the Official Google Blog, Google Suggest's feature set hasn't changed much in the four years since its debut in Google Labs. The three primary focuses of the feature as a whole are to "help formulate queries" by fleshing out incomplete phrases, "reduce spelling errors" by automatically fixing them in the suggestion drop-down area, and "save keystrokes" by predicting what you're going to type. We've used the features in the past and their wide adoption in other products means they're a no-brainer for increasing search efficiency.

We can't get our hands on their current implementation, however, as Katie Watson, a representative from Google's Global Communications & Public Affairs, told Ars Technica that "This feature is gradually rolling out over the course of this week. Some people might not be able to see it until as late as Friday, so it could take some time." So if you're dying to have Google suggest search terms, you may have to wait a few more days.
