Module 4 - Boolean Searching Task

Discuss your strategies with the class and record the exact search terms you used in your learning log

There are a number of strategies that can be used when searching the web. The Boolean search strategy provides a way of searching for information and gaining exactly what you want out of your search rather than having to sort through pages that are not relevant. The strategies that can be adopted are as follows;

Use OR to gain as many hits as possible, the results would contain either of the keywords. For example n the prior task I had searched the word Netiquette. To gain more hits I then searched Netiquette OR Internet guidelines. This resulted in 21,200,000 hits whereas the first search only resulted in 10,600,000 hits.

Use AND to ensure that both of the key words are present in the search results. For example when searching for information on the concept of netiquette I searched Netiquette AND guidelines. This enables the search to be narrowed down to specific material. This search resulted in 338,000 hits.

There also may be times when you do not want a particular key word in the search. For example netiquette may turn up some hits that have etiquette present in the page. The way this can be achieved is by adding NOT into the search. For example I searched Netiquette NOT etiquette. This search resulted in 117,000 hits.

BY adopting all of these strategies I was able to maximize my search and gain all that I can from the search. There are times when searches turn up pages that are not relevant and as a result it is necessary to change the search to minimise the amount of hits in the results.
