Bing

Bing is Microsofts attempt at unseating Google. Bing used to be MSN search until it was updated in summer of 2009. Touted as a decision engine, Bing tries to support your researching by offering suggestions in the leftmost column, while also giving you various search options across the top of the screen. Things like wiki suggestions, visual search, and related searches might be very useful to you. Bing is not dethroning Google in the near future, no. But Bing is definitely worth trying.
