DENVER -- We all have our favorite search engines when we're accessing the Internet, but if you get into the habit of only using one search engine all the time, you might be missing some relevant results.

So how can you avoid bookmarking all of the search engines you need to find exactly the Web page you're looking for?

Well, let Mr. Sapo do the work for you. With this site aggregator, you can access the 80 top-performing search engines all on one page.

If you want to do a basic search, you just type in the search term at the top and click on the search engine you want to use. The advantage here is that you don't have to open a new page to compare the results you get from Google, to the results you get from Yahoo, All The Web, or MSN.

The site can also help you narrow your search by using sites that specifically look for images, audio and video, academic articles, news articles or blogs.

For instance, if you search for "Denver" images in Google, you will find that the images that show up will be a lot different from the ones you get by searching Getty Images. Getty's images are more professional in nature and often requires you to purchase the image to use it --- but if a more polished look is what you're looking for, then you've found the answer.

The same is true if you're looking for an obscure medical article. If not a lot of sites have linked to this article, it will not show up in the search results, but using perhaps an engine that searches scientific journals such as Scirus can.

"Search engines differ from one another more than most people think. They differ in the way that they gather and store information, the algorithm they use to match and rank the results and their level of sophistication; hence by using only one search engine, Internet users are potentially missing relevant results," Mr. Sapo said.

So whatever you're looking for, Mr. Sapo can help you find it. If not, at least it can help you navigate the Web better.

And if you are still thinking that Google will always be good enough for you, think about this: The Web is now so huge -- about 15 billion pages or so -- that no one single search engine can cover more than 15 percent of it.

Mr. Sapo said that overlapping results between search engines is low. According to its own tests, using the 100 most popular search terms, Google and Yahoo shared only 3.5 of their top 10 results on average.
