Google mobile search
The man in charge of the Google mobile mission is Dipchand “Deep” Nishar. He believes that when people are out and about, they want very different answers from Google than they would if they were sat in front of a PC.

For instance, he said, the first result that comes up after typing “film” into a PC browser is the Internet Movie Database.

“But type ‘films’ into a mobile browser and you are most likely going to see a movie,” he told the BBC News website.

“The same search query, because of the context, means very different search results,” said Mr Nishar. “Search on mobiles is about finding not browsing.

This means that Google has to slice its huge corpus of data differently for mobile users and tailor results to where people are sitting or standing when they make the query.

What is also important to realise about mobile devices, said Mr Nishar, is that they are far more personal than a home computer.

“A PC is much more of a shared device,” he said. “But a mobile is not something I share with anyone.”
