Information caption:
Analyse your research topic
Scenario: Your lecturer has set the following essay topic:
Discuss how social media is affecting the recruitment practices of employers.
You are required to refer to relevant academic journal articles and news articles.
Understanding the topic

[pic]
Information caption: Before you start searching a database for journal or news articles, make sure that you understand the topic and what you are being asked to do.
Instruction caption: Click each item below to read more
Feedback caption:
Button: Background reading
Background reading is important for
• gaining an overview of the research topic and an understanding of relevant concepts
• identifying potential search terms
Your background reading may also point to further initial sources of relevant information.
When researching for a unit assignment be sure to read any relevant readings your lecturer has recommended as well as the relevant sections of the unit textbook(s).
Button: Definitions
Check an encyclopedia, dictionary or relevant textbook for precise definitions of terms.
Two examples of leading dictionaries which have online versions are Macquarie Dictionary and Merriam-Webster Dictionary. Both include a definition of “social media”.
Library guides often list subject-specific or specialist encyclopedias, such as those comprising Blackwell Reference Online.
Button: What are you being asked to do?
Be clear about the actions required to respond to the topic.
Discuss – consider the aspects of the topic and provide a point of view, based on authoritative evidence.
Depending on the topic, you may be asked to “analyse”, “compare and contrast”, “evaluate” etc.
If you are unsure of exactly what is required, consult your lecturer or tutor, or a Library Learning Skills Adviser.
For this topic you are also required to refer to relevant academic journals and new articles, as evidence in your response.
Identifying the concepts
Image : Quiz screen showing the essay topic
[pic]
Information caption: What are the key concepts in this essay question?
Instruction caption: Click on the key terms in the topic
Information caption: Topic sentence: Discuss how social media is affecting the recruitment practices of employers
Feedback caption: Key terms are social media, recruitment and employers
Terms which are not key terms are discuss, affecting, practices.
Synonyms and related terms
Image : Synonyms and related terms
[pic]
Information caption: The key terms alone may not be enough to form a successful search strategy. Use synonyms or related terms or phrases, which will allow you to create a more comprehensive search.
Instruction caption: Point the curser at each item below to show some possible alternative terms
Information captions:
Social media: social networking sites, online social networks, Facebook
Recruitment: recruiting selection hiring
Employers: employees, human resources, staff
Quiz 1: Synonyms and related terms
Image : Matching related terms quiz
[pic]
Information caption: The three terms in the essay question may not be enough to produce a successful search result. Using synonyms of related terms (alternative words and phrases) will help widen the search,
Instruction caption: Click on the boxes to match the alternative terms with the terms from the essay topic. Then click Submit. Click Clear to start again
Instruction caption: Click press next or back to continue
Feedback caption:
a) Social Media - Facebook is a social media service
- social networking sites is an alternative phrase
- online social networks is an alternative phrase
b) Employers - is related to enterprises and also to businesses
c) Recruitment - is closely related to “staff selection”, recruiting and hiring.
For each of the three key terms there may also be other related terms which have not been listed here.
Phrases, truncation and spelling
Image : Female student deep in thought and click buttons for definitions
[pic]
Instruction caption: click each item below to read more
Information caption:
Phrases: two or more words used together to form a single concept
(e.g. social media)
Phrase searching can help to narrow your search.
Some databases automatically treat a string of words as a phrase, and search for an exact match for that phrase. Other databases search for the words individually, which results in a broader and less precise search.
You can ensure a phrase search by enclosing the phrase in double quotation marks.
Example “social media”
In some databases you can select a search option to specify that the entered words are to be searched as a phrase.
Truncation: Sometimes you may want to broaden a search by abbreviating a search term to its stem and then searching for its various endings.
In many databases you can use a truncation symbol to represent these endings. The most common truncation symbol is the asterisk (*).
Terminology and spelling: The articles and other content in a database are usually collected from a wide range of publishers, so expect spelling and terminology to vary according to the origin of the information.
For example
spelling: organisation/organization
behavior/behaviour
terminology: primary school /elementary school
In addition to truncation, some database search engines can allow for spelling variations within a word, with wildcard characters.
e.g. Entering wom?n will find both woman and women, helping to broaden your search.
Truncation and spelling

Information caption: truncate a search term to search for the root or stem word with all its various endings:
Instruction caption: Point the cursor at the terms below
Feedback caption: Recruit* : recruit, recruitment, recruiting …
Information caption: For search terms with multiple spellings you can often use a wildcard symbol:
Feedback caption: behavio?r : behaviour, behaviour
Principles of Boolean searching
Image : Introductory screen for Topic 2: Principles of Boolean searching.
[pic]
Information caption:
• Most databases require you to group your terms in particular ways
• Boolean logic refers to the way in which you combine terms to create a search statement
• The search statement includes or more of the three Boolean operators: AND, OR, NOT
Search options – AND, OR, NOT
Image : Boolean operations AND, OR, NOT

Information caption: Use Boolean logic to create an effective search strategy linking the key terms
AND, OR, NOT
Using OR: Broadening the search
Image : Using OR: broadening the search
[pic]
Image: Three green overlapping circles (a Venn diagram), with each circle representing the results of a database search on each of the three terms.
Information caption: As we have already seen, there are usually various ways of describing a term or concept, and depending on the database you are using, or the origin of the information, the terminology and spelling may vary.
Use OR to widen your search and catch the variant terms in a single search.
Instruction caption: Click the terms below to see the results of an actual database search for: “social media” OR “social networking sites” OR “online social networking”
The numbers represent the number of results found for each individual concept.
Feedback caption: Clicking on the term “social media” = 9,748 results
Clicking on “social networking sites” = 1,196 results
Click on “online social networking” = 743 results
The coloured area (total area of each circle) represents the total for the three concepts, which is 12,008 unique results.
Using AND: Combining the concepts
Image : Using AND: Combining the concepts.
[pic]
Image: 3 pale blue overlapping circles (a Venn diagram), with each circle representing the results of a database search on each of the 3 concepts.
The overlapped areas are a darker shade.
Information caption: We can use AND to indicate that all three terms from the essay question must be included in our search results.
This is expressed as: “social media” AND recruitment AND employers
This is a powerful way of focusing your search; that is reducing the number of results and making them more relevant.
Instruction caption 1: Click on the terms to see the results of an actual database search when combining: “social media” AND recruitment AND employers.
Feedback captions: clicking on the term social media” = 9,681 results
Clicking on the term recruitment = 78,834 results
Clicking on the term employers = 106,386 results
Instruction caption 2: click on overlapping areas of the circles for more information.
Feedback captions 2: 323 = the number of results which include “social media” AND recruitment
5,635 = the number of results which include employers AND recruitment
149 = the number of results which include ‘social media” AND employers
32 = the number of results which include all 3 terms. These are the most likely to be relevant to the topic.
Using NOT: Excluding a term
Image : Using NOT: Excluding a term
Image shows two overlapping circles, one red, one blue; the overlapping area is purple. The image represents the sets of results retrieved by searching on the terms “social media” NOT facebook.
[pic]
Information caption: NOT is used much less frequently than AND and OR, but can be used very effectively to exclude unwanted terms.
NOT should always be used with caution, as results which include both the desired and unwanted terms will be excluded. The search “social media” NOT facebook produces the set of results depicted by the red area.
The intersecting area contains results which have both terms, but using NOT excludes these records, even though some may also include useful information on social media other than facebook.
However, if you were searching for information about Melbourne, but not about Melbourne in Florida, you could search for Melbourne NOT Florida to usefully exclude any irrelevant information, since these topics are very distinct.
Some extra search tips.

Information caption: Some databases require the Boolean operators to be in upper case (AND, OR, NOT). If in doubt, consult the online help for this and other information on correctly structuring and entering a search in that database, or ask a librarian.
Although Google and Monash Search allow natural language searching,
for best results avoid directly typing your essay topic in the search box. Decide on the topic’s key terms and use Boolean searching instead.
Quiz 2: Broadening your search
Image : Tick the box quiz: “Broadening your search”
[pic]
Information caption: There are a number of ways you might increase the number of relevant results if you didn’t get enough in your first search
Instruction caption: Based on what has been covered in this module select all the options that would broaden your results
A) Check that you are searching a database relevant to the topic
B) Check for spelling mistakes or other errors in entering the search terms
C) Add a term (using AND)
D) Add a synonym or alternative term with OR
E) Make sure you are using the Boolean operators (AND, OR, NOT) correctly
F) Use truncations to find variations of your terms
Submit
Feedback caption: A), B), D) E) F) – Correct –any one of these options would help to improve the number of relevant results from your search. Click anywhere or press ‘y’ to continue.
C) Incorrect – all options except C will result in a broader search.
Click anywhere or press ‘y’ to continue.
Instruction caption 2: Please complete the quiz before continuing.
Quiz 3: Focusing your search
Image : Tick the box quiz: Focusing or narrowing your search.
[pic]
Information caption: If your search resulted in too many records, you will need to focus or narrow the search to achieve a smaller and more relevant set of results.
Instruction caption: Based on what has been covered in this module select all the options that would narrow the results.
A) Limit your search by date, document type or language
B) Remove a synonym (or alternative terms)
C) Add another concept or key term using AND
D) Use phrase searching where relevant
E) Search using more specific terms
F) use NOT to eliminate an aspect of the topic you are not interested in
Submit
Feedback caption: A), B), C), D), E), F) Correct - any of these options would help to reduce and focus the number of relevant results from your search, but some will do so more effectively than others.
.
If not all the boxes were ticked: Incorrect - all of these options would help to reduce and focus the number of relevant results from your search, but some will do so more effectively than others..

Information caption: Congratulations on completing “Developing a search strategy”!
You have been introduced to the steps for converting a research topic or question into an effective database search strategy:
1. Understand the topic/question. Clarify concepts, definitions, and what you are being asked to do.
2. Identify the key terms, and alternative expressions that will help to broaden the search and increase the possible number of useful results.
3. Use Boolean operators (especially OR and AND) to construct a search statement.
4. Perform the search and evaluate its results, looking for ways to increase the relevance of your subsequent searches. The tutorial included examples of several databases to show how search statement entry can differ between interfaces.
