It's the day before Thanksgiving and all I can think of is pie. Pumpkin. Apple. More pumpkin. And search market. Mmmm, delicious search market.

Microsoft saw its slice of the latter narrow from September to October, according to fresh-from-the-oven comScore stats.

In October, the company's Web sites accounted for 9.7 percent of the 10.5 billion searches conducted in the United States. That's down a bit from 10.3 percent in September -- definitely not the direction the company wants to be going in, especially if it hopes to achieve Platforms and Services Division President Kevin Johnson's "10, 20, 30, 40" goal. (The 30, as in percent, is the target for online search share.)

Yahoo also saw its piece of search pie get smaller, but it's still a comfortable second in the market with 22.9 percent in October, down from 23.7.

Google ate up 58.5 percent of the market in October, up 1.5 percent month-over-month -- just about the same amount that Yahoo and Microsoft, combined, were down.
