Search engine ABCs [The Data]

Start typing in a browser's search box and the search engine races to complete your query. It's a great feature that can save you a lot of time. Search engine providers don't reveal their algorithms, but the theory is that they base their guesses on what other people in the same geographic area have searched for when they type the same initial letter. But even within regions, what most people are searching for depends on what search engine they use.
