Logical operators/search engine

Introduction

I will be looking at different search engines in order to find the information that I am looking for. The information that I am going to be researching is house price data. I'm going to compare 3 search engines to see which one is most appropriate in what I'm looking for. Text based search engine: For this section I'm going to use Google as the text based search engine. In my personal experience many people use Google as their primary search engine. I'm going to search house price data in Google's search bar and see what results I get back from it. The index returned 125,000,000 hits relating to my topic. Directory search engine: For the directory search, I will be using the live search to see what results I get from the topic that I am researching. The results from the search came back with 67,200,000 hits relating to my topic. Meta search engine: For this section I'm going to use ask.com search engine. Ask.com is a little different from the other two search engines because it allows you to actually type a question in e.g. ...read more.

Google also uses the minus sign to represents the NOT operator. Effects of using logical operators Search Criterion What it looks for Number of hits House Price Any pages that contain the word House price. 166,000,000 House Price AND Data Pages that contain both words House price and Data. 47,900,000 House Price AND data OR Wages Pages that contain both the words house price AND Data OR Wages. 43,300,000 Advanced search options: This is another way of adding precision to searches. The advanced search is offered by many search engines, the search engine that I am going to be looking for the advanced search option is Google. Some of the options in Google's search engine are the same as using the logical operators which I have stated above. The option 'with all the words' is the same as the AND operator. The option 'with at least one of the words' is the same as using the OR operator and the 'without the words' is the same as using the NOT operator. As you can see from the screen shot I have taken, I used the Google's advanced search in order to find what I am looking for. ...read more.

Conclusion

The data that I downloaded from this on-line database was in Microsoft excel. House Price Data in Excel: As you can see from the screen shot the data is set out in four different sections which I have highlighted on in the screenshot. The first section is all houses, the second section is the new houses, third section is modern houses and the fourth is older houses. I will be using different functions in order to do some analysis to this data. I created a graph using the data I got from the spreadsheet. I took every forth column for the first 10 years to generate some analysis. As I stated above the nationwide data had four sections one of which I did a graph on in the screenshot above. I decided to take every 'Q4' of the three sections and compare them. I compared 'new houses' with the 'modern houses' and the 'old houses'. Again I only took the years from 1952 to 1961 because of the large amount of data within the nationwide. As you can see from the screenshot on the right the three different house sections are quite close together. The 'New houses' has the best increase then the other two. ...read more.
