Task 1

Using Search Engines 

Introduction

In this task I have been asked to research for a website by using a search engine that I think is best suitable for the research. In this research I will be finding a weather station website that contains forty years of data on rainfall. The reason for why I want this is because I need to see whether there has been a decrease or an increase in rainfall. In order to do find the website I will have to type in specific words and phrases into the search engine; to tell the search engine what exactly I’m looking for. As part of the task I will also have to use logical operators which are, AND, NOT and OR to search for the website.  I will be explaining each of the logical operators in detail below: -

AND: -

In search engines they automatically put this is a search so you don’t really need to put it in the search bar. So if you put in a search like ‘birds bees,’ it will put in AND to make ‘birds and bees’ and will only bring back websites that have ‘birds and bees’ in the website.

OR: -

In a search this would bring up more websites. For example if I put in a search like birds or bees, it will bring up sites with just birds in it, websites with just bees in it and websites that have both Birds and bees. So by using OR it brings back more websites.

NOT: -

By using NOT, it will dismiss anything I put after NOT. So for example if I put in a search ‘birds NOT bees’ it will only bring back websites that only have bird in the address, not bees and not birds and bees.

These logical operators work when they are in a capital.

+: - Using the +, it eliminates pages which do not have the words or phrases when placed in front of it e.g. snake +in +the grass. This search would bring back only pages that do have the ‘in the’ only. If these were not used, it would bring web pages that could be grass snake, snake grass, grass and snake.

“  ”: Using “  ” makes the search more specific and precise. Requires exact phrase in all the pages that the search engine brings back.  

Before I start I will also need to consider what search engine I will be using. In order to do this I will compare the three search engines that I think are best suitable for this type of research. Out of them three search engines, I will have to pick one that I think is best suitable out of the three.

Comparison of my three Search Engines

The three search engines that I will be comparing are:

I will talk about each search engine in depth and will be describing each one of them and comparing them with each other.

Below is a screenshot of the homepage of the Google website

This website is for use of quick searches that can be made very easily and the search engine itself is very simple to use. The Online service is open 24/7 and is very commonly used.

The key feature is that there are no pop-up ads and no untargeted banners.
You see only relevant text ads and links to related web pages of interest.

The website it self is very simple at first but there is further options if someone wants to enhance their search results by clicking on the advanced search hyperlink. This is located near the Google search bar on the right. Below is a screenshot showing the different features that the Google search engine provides.

The search engine also provides users to switch from the google.com search engine to google.co.uk. The screenshot above shows the website on google.co.uk and that is the reaosn for why there is an option for the user to switch from the google.co.uk search engine to google.com. The only difference is that the search result is returned with less pages, when searching on google.co.uk, for the simple fact that the search is made within the websites that are published in the UK only however google.com brings back ...
