Search for Images Using Google Image Search

Okay, here’s another function Yahoo! shares with Google—image search. When you access Yahoo!’s Search for Images page ( you’re actually accessing Google Image Search. That’s not a bad thing; Google Image Search is one of the best search indexes on the Web for photographs, pictures, and other graphics. If you want to find a picture of something, this is the search to use.

Yahoo!’s Advanced Search Page

As you just learned, Yahoo!’s Web Search is powered by Google, which means you can use all of Google’s advanced search operators to construct your search queries. If that sounds too complicated, you can perform most of the same operations using Yahoo!’s Advanced Search page. The nice thing about using Advanced Search is that you don’t have to remember those fancy operators. Just select the options you want from those listed and click the Search button;
Yahoo! does the rest.

You access the Advanced Search page by clicking the Advanced link next to a particular page’s Search button. Each type of Yahoo! search has its own specific Advanced Search page; for example, the Advanced Web Search page includes options specific to Web searching, while the Advanced
Directory Search page includes options for finding categories in the Yahoo! directory.

When You Search Yahoo!, You’re Searching Google

Okay, Yahoo! is known for its high-quality and well-organized Web directory. But when you use Yahoo!’s Web Search feature, you bypass the directory entirely and instead retrieve results supplied by a third-party search engine. That’s right. When you use the search box on Yahoo!’s home page, you’re not searching Yahoo!—you’re searching Google.

For some time now, Yahoo! has supplemented its directory listings with results from a partner search engine. Early on, Yahoo! offered results from the Inktomi search engine. Today, Yahoo! uses results provided by Google.

Do your own comparison. Enter a query into the Yahoo! search box, then go to Google ( and enter the same query. The results should look familiar.

Since searching with Yahoo! is the same as searching with Google, you can use Google’s advanced search operators when you conduct a Yahoo! Web Search. These operators help you fine-tune your search by including or excluding specific words, searching for exact phrases, and narrowing your search to certain sites or domains. There’s no point in repeating those operators twice in the same book, so turn to Chapter 6 to learn more—then utilize those advanced search operators the next time you construct a query on Yahoo!.

The Yahoo! Directory Has Higher Secret Higher Quality Results than Yahoo! Web Search

Yahoo! was created as a hand-picked directory of Web sites. Over the past decade, however, the Yahoo! directory has become a less and less important part of the Yahoo! pantheon of services—to the point where many users don’t even know the directory exists. After all, if you use the search box on the Yahoo! home page—which Yahoo! obviously wants you to do—you pass over
the directory entirely.

That’s too bad, because the Yahoo! directory is actually a pretty good assemblage of what’s out there on the Web. It’s also arguably the easiest search site for Web surfers to use.

It all boils down to the basic difference between a directory and a search index You see, there are two approaches to organizing all the information on the World Wide Web. One approach is to use a special type of software program (called a spider or crawler) to roam the Web automatically, feeding what it finds back to a massive bank of computers. These computers hold indices of the Web—in some cases, entire Web pages are indexed; in other cases, only the titles and important words on a page are indexed. This approach is the one taken by the big search engines, such as Google, AltaVista, and HotBot—and by Yahoo!’s Web Search feature.

The other approach—the one taken by the Yahoo! directory—is to have actual human beings physically look at each Web page and stick each one into a hand-picked category. After you get enough Web pages collected, you have something called a directory.

Unlike a search engine, a directory doesn’t search the entire Web—in fact, a directory catalogs only a very small part of the Web. But a directory is very organized, and very easy to use, and lots and lots of people use Web directories (such as Yahoo!) every day.

Of course, that’s not to say that the Yahoo! directory is perfect. Far from it. For starters, it’s small—only 2 million pages, versus 3 billion or so in Yahoo!’s Google supplied Web Search index. (That means that Yahoo!’s directory content represents less than 1⁄10 of 1 percent of the total number of pages currently published on he Web—not very comprehensive at all.

Fortunately, you don’t have to limit yourself to the listings in the Yahoo! directory; Yahoo! supplements its directory listings with search results from a thirdparty search engine. Read on to learn another little secret about Yahoo!’s search capabilities.

Use the Direct Address

Even better, almost every Yahoo! service has its own unique URL that you can enter directly into your browser’s address box, or bookmark as necessary. You might think that remembering dozens of unique URLs would be difficult. And, of course, you’d be right—if you actually had to memorize the URLs. Fortunately, Yahoo! uses an address scheme that’s easy on the old memory, thanks to its common-sense nature. Yahoo!’s address scheme is simple. Just take the domain and add the service name in front of it, like this: service.Yahoo! .com. So, for example, if you want to go to Yahoo! News, you enter If you want to go to Yahoo! Mail, enter

Go Directly to Almost Any Yahoo! Page

Well, you can access most of these services from links located somewhere on Yahoo!’s home page—if you can find the right link. If you can’t find a link to a particular service on the home page, scroll down to the bottom of the page and click the Even More Yahoo!’ link. This takes you to a page that lists every site and service that Yahoo!’ offers.
