Internet Searching – Search Engines

You may know the URL of the site that you want to visit.
URL stands for Uniform Resource Locator, it is also called the web address, or www address or site name. They usually begin with http://www, but not necessarily.


However, you may not know any names of sites you want to find. You therefore need to go to a site that will find other sites for you.
These are called Search engines. Here are some of the most famous:
http://www.google.co.uk
http://www.ask.co.uk
http://www.yahoo.co.uk
http://www.altvista.co.uk
http://www.msn.co.uk


There are hundreds of others, so try and use a variety and you will get different results. Some people prefer the different results that you get on certain search engines.

Advanced Searches

You usually type in a word or two or a phrase and hit search, however if this does not get you the site that you want, or gets you too many sites, you will need to do an Advanced Search. Let’s use google to demonstrate. Go to http://www.google.co.uk.
When you type in two words, for example Crisis Skylight, google finds all the webpages on the web that contain both those words at least once.
This gives you about 35,000 pages to chose from.
Google then lists all the pages that have “crisis skylight” together as a phrase, then it will list all the pages that contain “crisis” and “skylight” separately.

We want to be more specific about our search, so we need to do an Advanced search. Hit the Advanced Search link to the right of the Search button on google.
You will now see more options for how to search.
with all the words Crisis skylight
with the exact phrase “Crisis skylight”
with at least one of the phrases Crisis OR skylight
MUST BE CAPITAL OR
without the words -energy

On the right are how the search appears in the google search box. Other sites have similar Advanced Searches, except the symbols may be slightly different.
You can do advanced searches directly by simply typing in the symbols.
Google Advanced Search has these other features:
Language
File Format
Date
Occurrances
Domain
SafeSearch
Similar
Links


Google is also intelligent and will recognise certain phrases, for example if you write “What is a an MP3” It will convert that to define:MP3. It probably had loads of these, but I don’t know any more.Here we have been searching the Internet.

I now want us to search a database on a website. It is very similar, but only draws data from the server of this company
Go to www.gojobsite.co.uk


We will do a basic search, then a refined search.
Put in teacher IT and hit return.
All adverts on this site that contain teacher or IT in it come up.
Now hit refine search and we'll extend the ideas we have just seen on Google Advanced Search.
Put in London as the Location. Select a "within...miles" options.
Select Contract Jobs and also only today's adverts.
Now keep doing refine search to get different results.
