Internet Search Services

Too much information available online can be
frustrating. Some authorities estimate that the number of entries on the
Internet is estimated at 800 million. Some say that the number is unknown.
Fortunately, there are tools available that will filter by quantity
information: search engines or search indexes.
Search engines collect information from Websites
and, more or less, simply drop that information into a database. There are some
details to choose from in the search engine, but it is very difficult to find
relevant information.
Search indexes attempt to add a sense of order
to the information they collect and you may find relevant information for your
search title, but they do not provide the maximum amount of information that
you can find on a search engine. Collected sites are viewed by decision-makers
about which categories of topics can be categorized.
Search engines
Search engines are the largest source of
information about where information is stored from Internet documents. The
information in this database is collected using a computer program (called a
"spider" or "robot") that scans the Internet and collects
data in individual documents. These special programs work automatically to
obtain documents or request by the Website Builder to visit the site for
inclusion in the database.
When you search for a search engine, the type of
search results also vary between search engines. Many engines calculate results
using compliance. Features such as:
Terms of your search terms are often used on a
Web page;
where they are found on the page; and,
How many other Web pages are linked to a page
... influence how high a listing page list is
listed. Many search engines allow websites to pay to have their pages indexed
in results.
There are hundreds of these search engines
available on the web, but they all work in different ways to collect and
organize search results. Information from Websites can be collected from all
site names, the first few sentences in the body of the site, or only in the
title or metatags (hidden descriptions of site content). Different search
engines collect different information, which is why you will find different
results in the same search from different search engines.
Search for directions
Directions are best used if you want information that can be easily sorted, such as "Georgian Universities and Colleges." You can find the information you need without having to type a search, but by browsing the guide, starting with the most comprehensive section (Education) and working your way up the index to certain lists of Georgia schools. You can perform standard searches as well, but the indexes do not compile the same list of sites that a search engine would like you to find out as much as you can find in a search engine.
GALILEO also has a database of useful Websites
tested by teachers. These sites are not posted by an engineer and are not
harvested by spiders. Deliberately selected for their research application in
the curriculum of the University System of Georgia.
Meta search Engines
This type of search services provides a kind of
"single purchase" on the Internet. You can create one search and the
meta search service will send the search to multiple search engines and indexes
at the same time to get results all in one place. The only problem with this is
that you only get the first few results for each list. If the site you are
looking for is ranked 10th in the search results results area and the meta
search engine only gives the first 5 results from this list, then you will not
find the site you need. If you are trying to get a general idea of what information is available on the web,
then a meta search engine can be a good place to start.

Any information you use to support ideas and
arguments in the research paper should be carefully considered. The printed
material collected in the library goes through a process of testing as the
librarians choose to put it in their collections. There are also tests of
websites included in search guides, such as Yahoo !, at least to the extent of
classifying and placing sites in the classification system. However, sites
harvested by “spiders” or “robots” in search engines do not go through any
testing process.
There are no actual restrictions or editing
procedures for publishing information to the Web, in addition to the basic
information for creating a Web page and accessing the host computer. Anyone can
publish an opinion, sarcasm, fraud, or false information. To ensure that the
Websites you use as a source of information are acceptable for research
purposes, you should ask questions about those sites. The following are some
things to consider before deciding to use the Web as a research tool:
