Search engine Ask has had another makeover in an effort to gain boost the numbers of people using it.

The relaunch follows the decision to drop its iconic butler at the beginning of 2006 and the introduction of new applications last year.

Ask will be refocusing on its ability to act as the search engine of choice for those asking questions.

Rivals are increasingly looking at ways to set themselves apart from Google in the competitive world of search.

Data from net measurement firm ComScore found that Ask is more often used by people searching for specific answers to questions.

While such questions account for about 5% of queries to Google, Yahoo and Microsoft Live Search, it accounts for 15% of Ask's searches.
