If you have visited the Google.co.uk homepage (Yes, that’s Google UK) recently – since about the 8th of September 2010 then you would have noticed a new search feature Google is pushing called Google Instant.
Now what is so nice about Google Instant?
It is an ajax type search application that now searches using keyword ghosting and searches and returns results as you type to populate the normal search results page that has been used up until now.
You can enable it over here if it does not appear for you or you have mistakenly turned it off.
Also note that you will need to be signed into Google Accounts in order for this to work at the moment. This will probably become something that you won’t need a Google Accounts for once it becomes a default google feature used on all the worldwide homepages.
