Tech notes: Bing v Google

SInce its debut a few weeks ago, Microsoft's search engine Bing has received a lot of respectful press attention, from sources that range from David Pogue of the NYT to Derek Thompson of our own Atlantic Business Channel.

I agree about the attractive potential of many Bing UI features. But in the last while I've tried using it as a tool for actual work, and have found one consistent result: It doesn't cover as much data, or comparably fresh data, as Google does. An illustration that came up just now:

For reasons I won't get into, I wanted to track some recent comments by one-time NY Lt. Governor Elizabeth "Betsy" McCaughey about the Obama Administration's health care proposals. Ms. McCaughey has had three big moments in the spotlight in talking about medical care. One happened in the early Clinton years, when she was a prominent (and, as I argue here, completely misinformed and destructive) voice opposing "Hillarycare." Another was early this year, when she again launched a willfully misinformed attack, this time on "Obamacare." The third is just this month, when she has come up with another wild assertion about provisions of Obama's plan.

I wanted to track what she'd been saying recently, so I went to both Bing and Google and entered "Betsy McCaughey Obama health care proposal." The side-by-side results are below, from the very useful Bing-vs-Google site. Click for legible full-screen version:


What you'd see if you could read these listings -- and what you'll probably see if you run the same search for yourself -- is that on Google all of the first screen and most of the next few are about McCaughey's recent comments. The top hit was 8 minutes old when I ran the search. But the lead items on Bing and most of the first screens are about her comments back in February. The first item there is from February 9, and there isn't much at all about what she's said this summer. (If you run the search again now, Bing might have caught up.)

I have found this in other searches too. Bing's approach is interesting and can be useful. But it just doesn't seem to cover as much stuff. I'm always skeptical of the significance of "total results found" in any search engine. But the different you can see on the screenshot above -- 24,700 for Bing, versus 426,000 for Google -- feels about right as a gauge of the difference in the two systems' scope.

Yes, yes, too much information can be as bad as too little. Yes, Bing is presenting itself as a "decision" tool rather than a pure search engine. But most of what I do is outright searching, and for that it does not yet seem a real contender.

(Offsetting disclosures: I once worked at Microsoft; I have good friends both there and at Google.)
