The World Wide Web is so enormous and spread out that one of the hardest parts of learning to use it is figuring out how to find the information you need!
This is why SEARCH ENGINES were invented. Search Engines are programs which quickly check lists and indexes of thousands or millions of electronic documents looking for the information you need.
Which Search Engine should you use? Which is best? My personal advice is to try out several, and use the one which works best for you: the fastest, easiest and most effective. There are many good guides to search engines in the WWW. They compare things like speed, size and relevancy of results.
How do different search engines find and rank their results? Here are some of the things they compare:
| 1)
Page titles 2) Keywords 3) Search Text 4) Word Placement and Frequency 5) Advertiser Preference |
6) Hits |
A good example of differing search approaches can be seen by comparing Google and Overture, which are owned by the same company. Google claims to use a straight merit-based formula involving hits, links and relevancy. Overture simply sells placements to companies at rates which vary according to how many visits they get. Try this comparison exercise:

Sometimes we need to find PEOPLE, not THINGS. The best place
to look for people on the web is at
the
Internet White Pages. It includes many thousands of people, but not everyone
who is on the net.
To see how it works, try looking for yourself. Enter your local address, and see if you are in the 411 database. If 411 can't find you, you may want to follow the easy registration instructions at the 411 site. Then other people who are looking will be able to find you.
Now, try the People Search Exercise.....

One of the hardest parts of doing successful searches is deciding what search terms to use. If you search for a word or phrase which is too general, you will get thousands of results, too many to examine all of them. If your search is too narrow, it may not find anything. To practice forming search queries, try this FORMING A SEARCH EXERCISE.
If your first attempt to find something returns no results, or results different from what you are looking for DON'T PANIC! First, check your SPELLING. This is the most common cause of unsuccessful searches. If that's not the problem, try some alternate terms or words. For example, if your search for "skin-diving" returns nothing, try "scuba diving".
