If you start to type in the Google search box Google will suggest popular searches that begin with the letters you typed. This is what I got when I typed the different letters of the alphabet. No I don’t know what Zillow is.

Interesting! I’ve done something similar for various combinations of letters, but I’ve never tried the whole alphabet. I just tried A-Z and got the same results that you did. I suppose that is to be expected, but I’m guessing it varies by region, since these are all words recognizable by English speakers. If I were in France, I bet I’d get different results. (I just remoted in to a PC in North Korea and tried it, but every letter comes up the same thing: “Kim Jong-il”
By the way, Zillow is a real estate web site. It probably has many uses, but it’s a great site if you want to find out what a house has sold for.
