It takes experience to consistently get useful results from searches. The more you search, the better your results will be, and the easier it gets.
One of the things you'll learn about "search" engines is that they don't actually search the Web. They search their own database, which is built up over time using a Web crawler or spider -- sound backward to you? What's a crawler? Try searching for web crawler and see what you find.
That's now easy to answer. Try a few, and see which ones you like best.
Google is the 800 pound gorilla of the search business. It is good at producing relevant results.
Yahoo! and MSN Search and are the main contenders. They, and many other search sites have emulated Google's lean, clean look. They often produce results that are more relevant than Google's.
Ask.com is nice because you can enter your search terms in the form of a question. Try "How high is the Eiffle Tower?" (without the caps or quotes) or something else that you've always been curious about.) You can do the same at ixquick -- look for their "Natural Language" feature.
AlltheWeb offers a variety of specialized search tools and advanced search features.As the name implies, Metasearch engines query several major search engines. Then they combine and rank the results following some algorithm.
Previewseek, or just Seek, is a stunning new metasearch engine from England. Ordinary search engines often give you so many results that it's tough to find the relevant ones. Previewseek overcomes this curse by sorting the results into categories. You simply pick the relevant category, and you're instantly mining much richer ore. Tip: Sometimes you need to click "Show More" under the list of categories to get the one you want.Dogpile has been around since the beginning of metasearch, and it has continued to evolve. They combine results from Google, MSN, Yahoo!, Ask Jeeves and others. Don't overlook the View Demo link (tiny text). By clicking the Google, Yahoo!, etc., links you can see side-by-side comparison of what each engine finds. Naturally, the composite that Dogpile creates is much more comprehensive.
I searched for "I'm your huckleberry" using Dogpile, looking for some history of the expression. One category that AllinOne listed was Doc Holliday, which gave me exactly what I was looking for.
AllinOne MetaSearch is another search engine that uses categories to do the work of refining your search for you. I'm not sure which one, Seek or AllinOne is most effective. Advice? If you don't get what you want from one, try the other.
Explore search sites thoroughly. They all do much more than what the opening page shows. Be sure to look at "Advanced Search" at the site. You'll be surprised at what you can do at a search site these days.
All of these search engines can give good results. It's well worth your while to try more than one if you don't get the results you want right away though.
Some spiders don't revisit sites for a long time. The linked page, or even the site itself may go away before the spider gets back to check. That's why you often find dead links in search results.
Many people find that an Internet directory is an easier way to find things on the Web. Directories are created by humans rather than Web "spiders", which just blindly index the words on the Web. Search engines are powerful, but people see relevance and connection much better. The directories at dmoz.org, Yahoo! and Google are among the best.
