In terms of user experience, the gap between the major search engines and their alternatives continues to widen -- a lot. Google has been compared to a luxury liner that turns around very, very slowly, whereas the startups are speedboats that can turn (or innovate) on a dime. I guarantee that if you try any of these top 10 alternative search engines of 2008, you won't come away saying, "Hey, that was just like Google."

As evidence of just how much the landscape is changing, three of our top 10 products require one-time downloads: once thought to be the kiss of death when Google sits in wait. But AltSearchEngines thinks that 2009 will be the tipping point when the rewards outweigh the "risks," at least for power users. For everyone else: 2010. Faroo, KallOut, and Surf Canyon (and, again, Tazti) are all well worth leaving your comfort zone for.

How many of these 10 search tools had you used, seen, or even heard of before today? The latest data from Hitwise shows that the four major search engines get over 98% of all US search traffic; the rest, combined, get less than 2%. These wonderful inventions need and deserve more exposure, so do your part and take the time to try out each one! On that note, let's begin.

This is the ninth in ReadWriteWeb's series of top products of 2008:

• Top 10 Semantic Web Products of 2008
• Top 10 International Products of 2008
• Top 10 Consumer Web Apps of 2008
• Top 10 RSS and Syndication Products of 2008
• Top 10 Mobile Web Products of 2008
• Top 10 Enterprise Web Products of 2008
• Top 10 Real World Web Apps of 2008
• Top 10 Digital Lifestyle Products of 2008

Note: these 10 search engines are listed alphabetically.

1. ChaCha

ChaCha, as a search tool, is human-powered, general, and mobile. There is no website, no search box, and no page witih a list of ten links. To use ChaCha, simply call 1-800-2ChaCha (1-800-224-2242) in the US, or send a text to 242242. When you call, leave your query just as you would any other voice-mail message, and hang up. Within 2 to 5 minutes, a human guide will have researched and texted you the answer. I used ChaCha with only my cheap cell phone when I was lost in New York City at midnight. And that's an important point: you can call ChaCha at any time with any question for any reason on any phone -- as long as that phone can receive text messages. And, aside from your carrier's incoming text fees, ChaCha is free. We recently reported on ChaCha over at AltSearchEngines.

2. Cooliris

2008 was the year when search visualization met the iPhone. Cooliris has already won one ReadWriteWeb award, making it onto the list of the Top 10 Consumer Apps of 2008. RWW wrote in that post, "Visual browsing is still coming into its own, but Cooliris is leading the charge in a way that consumers will embrace." We at ASE have been following Cooliris since its PicLens days. Following right behind are SearchMe and Viewzi. Each of these three visual search engines displays your search results beautifully and fluidly on your iPhone, but with different styles, so you might as well download all three and experiment. There is a demo video on each site.

3. Faroo

Alternative search engines need at least one thing that differentiates them from the major search engines. Faroo, for its part, turns your conception of search around 180 degrees. Instead of one giant company (say, Google) storing billions of web pages on thousands of servers at a cost of millions of dollars, Faroo, now in public beta, relies on the P2P (peer-to-peer) network, which connects Faroo members with each other through their PCs. The result is an organic-looking web that can grow as the Internet grows, but without the need for massive server farms. So, check out Faroo by downloading it here.

4. KallOut

KallOut was one of our favorite discoveries this year, as we noted in the ASE review. Once again, it's time to put away that image of a rectangular search box! It's 2008! With KallOut, you don't have to stop what you're doing and mess around with a toolbar, tab, or window. You simply drag your cursor over content with your mouse, and KallOut performs the search for you right there -- literally, right there. Download KallOut here, and then practice a bit until you get the hang of it. No, it's not a harder way to search; it's a more efficient way to search. You'll see.

5. Kosmix

Kosmix is, in a way, an evolution of the old meta search engines. Kosmix answers your query with a long tabloid-like page of results in every possible category you might want. There are multiple news sources; images from various sites; audio from SeeqPod; opinions from Omgili; video from Truveo; info from Mahalo and Snappyfingers; plus content from all of the major sources, such as eBay, YouTube, and Wikipedia. Just about everything! For every search query, you essentially get an on-the-fly multimedia encyclopedia laid out on one page. Kosmix recently came into a little money, too. (Disclosure: Kosmix is an AltSearchEngine sponsor.)

6. Mednar

We had no idea how many health search engines there really were until Hope Leman started covering them on AltSearchEngines. Mednar is one we're particularly fond of: "I am in jaw-dropping, stupefied awe at the general excellence of the products of his (CEO Abe Lederman's) firm. Anything that saves all of us time as we hunt for relevant data amidst overwhelming amounts of information on every conceivable aspect of disease day after day catches my attention, and it has been caught today by Mednar."

7. Quintura

When you search with Quintura, you'll see a two-dimensional tag cloud (i.e. not a list). The other words in the box are there to allow you to explore concepts related to your original query. See something you hadn't thought of? Click on it and the cloud re-orients itself around that new term. You can delete irrelevant terms as well. But don't worry, it also provides a traditional list for you, just in case. Quintura is now available in several language "flavors" as well! Content publishers should investigate Quintura for possible use on their sites. (Disclosure: Quintura is a sponsor of both AltSearchEngines and RWW.)

8. SeeqPod

Speaking with SeeqPod's CEO Kasian Franks, I was shocked, shocked, to learn that not everyone owns an iPhone! Apparently there are millions of people who have nice smart phones that run something called "Windows Mobile." Anyway, SeeqPod has been constantly improving its music search engine ever since we came across it. And now, it can be installed on millions of smart phones that use the Windows Mobile platform (v.6.0 or higher). This, as RWW noted the other day, "is a bold move from one of the most innovative companies in online music. The SeeqPod API is already one of the most popular for third parties to integrate streaming music into other apps, and the company seems to launch something unexpected every month. This has got to take the cake, though."

9. Surf Canyon

Can I say it again? Search, after ten years, is no longer that ubiquitous box in the middle of the web page. In 2008, it gave way to innovative search tools that integrate useful features in new ways. Surf Canyon is also a download. I wonder how many commenters will say that no one will download an app? (Sigh.) The reason it's worth the download is that it turbo charges your regular searches. Surf Canyon actually watches what you do -- and don't do -- and what you click on, and it instantly pulls search results from deeper pages (say, page 8) and brings them forward if it determines that they can save you time -- a lot of time. And if you're still hesitant about the download, watch the video.

10. Taggalaxy.de

What's this? A personal favorite? This write-up is just a sneak peek of Taggalaxy.de; the rest is up to you. Taggalaxy.de (in German) was created by a German graduate student for a class project. There are almost no instructions: I had to learn how to use it by clicking, double-clicking, dragging, and just playing around with it. But I can tell you this, once you've got the hang of it, find a dark room with a monster screen, and then perform a search. What you see will be not just an alternative search engine, but an alternative search galaxy!

So, there it is. In 2006, I began a mission to find every search engine, one by one. The resulting list of 100 Alternative Search Engines was published on ReadWriteWeb in January of 2007. Four months later, AltSearchEngines was launched by myself and Richard MacManus, with an index of 1,000 alternatives to the major engines. Since then, AltSearchEngines has published over 2,000 posts about, "the most wonderful search engines you've never seen." Having honed our search-engine-finding skills, I can tell you that this list of the top 10 alternative search engines for 2008 is as current as today's news. Want more? AltSearchEngines reports on important updates, features guest posts from search experts, and of course explores the as-yet-unseen search engines of 2009, every day. Come and join us!

With more information being published on the internet and different filters for interpreting this information being created, here's a look at a our picks of unique search engines that are making headlines and changing the way we search.

There's no question that Viewzi is a search engine of the future with a host of visual features. Viewzi is a visual search engine that's only gotten better since its initial public launch. What makes Viewzi so unique is the various visual viewing options that are available for users to view their search results. From the album and mp3 search view for music, to the 3D Photo Cloud and Celebrity Photo views, there's something for everyone with Viewzi.

SearchMe

Listed as one of Time magazine's best websites of 2008, SearchMe is a slick search engine with an advanced and intuitive interface. Search results are displayed as a gallery of images that allows you to see the page without having to click-through. Do a search on "Obama" and SearchMe will note that you're probably referring to the future presidential candidate Barack Obama. In doing so, SearchMe will present you with several related categories to narrow your search such as Politicians, Democratic Party, US Government, and Political News. SearchMe also provides users with the option to create stacks, or bundles of web pages saved for later. This is a highly unique search engine of the future.

Custom Search Engines

Rollyo is a service that allows you to create your own custom search engine. While we also recommend Google's service that offers the same concept, Rollyo is a little more user friendly. Users can enter up to 25 individual sites to roll into a custom search engine. If you sign up for the service you can make your custom search engines either public or private and add it to your Firefox browser.

Custom search engines are unique and valuable search engines of the future because of what you can do with them. Sarah Perez noted how you can build your own custom search engine with your bookmarks. You can also build your own custom search engine to search through the archives of your competitors and see if they've written about anything you'd like to write about. In essence, you're providing the filters for your very own personalized search engine by only searching the sites you'd like to see results from.

What Did We Miss?

While there are tons of alternative search engines, we'd like to know what you think will be unique search engines of the future. Don't just give out names. Let us know what you're using now and which search engines you expect to see being used a lot more in the future. For more alternative search engine goodness, we recommend heading over and subscribing to AltSearchEngines.

Here's a look at some of the best visual views that Viewzi offers...

Web Screenshot View

The Web Screenshot view allows users to view screenshots of the pages of search results returned by Yahoo only. Up to 20 results are loaded at a time for maximum performance. However, once you get to the end of the set, 20 more are immediately loaded.

Basic Photo View

If you're a fan of Flickr, the Basic Photo view is perfect for you. This view shows images from popular image sharing sites Flickr and Riya. While the default setting is to use both sites and display the search results in a small size, users have the option of enlarging the search results and also removing images from either Flickr or Riya.

Video x3 View

If you're looking for video results, Viewzi allows you to view results from Youtube, Blinkx, and Veoh. Tags from videos are listed nicely above the video results Clicking on a tag allows users to dim videos they don't wish to be included in the search results.

Simple Text View

The Simple Text view provides combined search results from Google and Yahoo search engines in typical search engine fashion, but with a small twist. For one, a small screenshot is provided to the left of each result. To enlarge the screenshot, simple hover your mouse over the image for a better view. Another feature that's displayed is the site's Compete.com ranking.

4 Source View

Get visual search results from all 4 of the top search engines with the 4 Source view. You can view up to 15 search results from Google, Yahoo, Ask.com, and MSN in a 5 x 3 area. Results are color coded and lettered with its corresponding search engine. Hovering over any of the provided screenshots gives users an enlarged image and a brief synopsis of the source.

Other great views include Amazon Book view, Everyday Shopping view, The Weather view, Celebrity Photo view, and a MP3 Search view.

Visual Searching In Style

With the variety of views at users disposal, there is something for everyone here. While we wouldn't crown it the next "Google" , it could provide a better user experience for casual web searching. What could make Viewzi even better is an optional way for users to create their own "4 Sources" view by providing a way to search their favorite news sources in style. All in all, Viewzi seems to be a solid visual search engine.
