Which search engine do you use most frequently, and why?
I use Google mostly because I like the bare-bones page-with-text-box interface (that must have taken great effort to design!). I also like the way the results page is formatted. But that’s about it. Sometimes I use Bing and to my unscientific eye the results are identical, and performance the same.
When Google search came, its algorithms were lauded as prodigious. Have the other providers now created equiperformant algorithms? There has to be some difference between Google’s and Microsoft’s search algorithms. They cannot be identical in all respects.
Anybody here would know how they differ, and if they do, their relative strengths and weaknesses? And maybe this is completely stupid, but do they share some code under some arrangement, and customize on top of that?
