Overture to buy more search power to fight Google

Overture Makes Another Move to challenge its chief rival Google by agreeing to buy the Web search unit of Norway-based Fast Search and Transfer for as much as $100 million — its second acquisition in a week.

Overture said last week it would buy search pioneer AltaVista for $140 million. Overture said it hopes eventually to combine the three technologies to fine-tune Internet searching for businesses and Web surfers.
