Introduction:Successful searching of electronic or computer databases depends on:
1. You should search for the keywords or subject terms describing each concept separately, and then combine them to find references that include all the terms you have searched. It will make your search more flexible as you will be able to add or remove keywords from a set without affecting the other sets. 2. Use truncation to include plurals or variant endings. Truncation refers to shortening a word or eliminating some characters from a longer term to pick up variants. Truncation symbols, such as (* ? $), are used during the search to indicate to the computer to substitute any character(s) for the symbol. Truncation symbols vary from database to database. Example of truncation Use MANAG* to retrieve MANAGE, MANAGES, MANAGEMENT, MANAGING, (it will also retrieve manager, manageress, managerial, managerially, managership, manageable, manageability, manageableness, manageably) Take note that truncation may result in retrieving terms not relevant to your search. Example CAT* will retrieve CAT and CATS but also CATALOGUE, CATAMARAN, CATHEDRAL and many more unwanted terms if your concept is "cat". 3. Use Boolean
logic operator OR to broaden a search by inclusion. It is used to include synonyms,
related, broader and narrower terms describing the different concepts. It will combine the
terms listed vertically in each column of the concept map.
Combining sets: The next step after doing the initial search is to combine the results of those searches. This should be done in a way that reflects the concept map of the original query. Use Boolean logic operators AND, OR, NOT to combine results. OR broadens a search by inclusion. It is used to include synonyms, related, broader and narrower terms describing the different concepts. It will combine the terms listed vertically in each column of the manual search strategy planning example. AND narrows a search by combination. Something from each concept must appear in the reference to be retrieved. It is used to combine all the concepts. NOT narrows a
search by exclusion. It excludes any references containing the specified term.
Displaying results: You can display the results once you have done a search. The display methods and commands can differ from database to database. Modifying the results: If you find that you are retrieving far too many unwanted references, or nothing fits what you thought you searched for, you can try the following:
Printing or downloading the results: Once you have done a satisfactory search, you need to print or download the references. The print and download commands may require you to specify:
How to get access to electronic databases:The Library website provides networked access to the electronic databases subscribed to by the Library. Go to the Library website >> Databases & Article Searching. The Subject Guides page directs you to the relevant electronic resources for the various subject disciplines. General information is provided on each database, as well as help screens for searching techniques. | |||||||||||||||||||||||||||||||||||||
