Where to Search?
|While searching for supplements to your lessons, new web sites, or new ideas one could get lost in the abundance of information that is available on the web. As we all know not all of the information on the web is valid, and even less is useful. So how do you avoid getting lost in the abundance of information out there? Knowing where to look is just as important as knowing what you are looking for. Click the following links to learn about the different type of search tools are available on the web.|
Directories - This tool is organized and created manually by people. People ether submit or find sites and then create a description of them. The sites are organized by this man made description. Directories are sometimes organized in somewhat of an outline form. This is helpful to searchers that do not know exactly what they are looking for.
Crawlers- This tool is computer powered. After entering a topic in the search field it crawls through the internet searching for matches. This is the best way to find information that is ever changing or often updated. When a change is made in a website the crawler eventually finds it because it matches different topics.
Hybrids- As the name suggests hybrids are sites the have both human and crawler abilities. These sites are not uncommon and may be your favorite site. Most site favor one over the other but have the ability to do both.
Meta-Crawlers- This sometimes helpful, sometimes confusing tool doesn't crawl for search results. Meta-Crawlers search through many different search engines at once. This is a great way to check the validity of one source to another or compare different search results. You will also notice that each site list things in different orders. That great information that was on the fifth page of Yahoo results maybe on the first page of Google and if you had only searched Yahoo you may have given up by page two.
|What many people know as search engines are often very different. Sites with directories, crawlers, hybrids, and meta-crawlers are all sometimes labeled "search engines."|
