2. Your task
To conduct a literature search for a subject of your choice and present the search
results as a table. This task can be undertaken in pairs or alone.
TIP! Your papers should relate to your research question - they do not need to
answer it!

3. Advanced literature searching
Your search should aim to be:
Comprehensive – you should search a variety of sources including subject
databases, specialist collections (e.g. Cochrane) and key journals not indexed in the
databases.
Structured – you should use a methodical, consistent and structured approach to
search, refine, evaluate and select your articles.
Auditable – you should record your search so that it is transparent and clear how
you arrived at your results.

4. Steps in the literature search process
1. Identify the key concepts of your topic or research question.
2. Select appropriate search terms to describe these using synonyms, related words,
acronyms and abbreviations.
3. Apply standard search techniques e.g. AND OR, truncation, proximity operators etc.
4. Select appropriate databases to search e.g. Cinahl, British Nursing Database.
5. Refine your search results to primary research and apply date and language limiters.
6. Make your final selection from the remaining articles, applying your exclusion criteria.

5. Do not select articles from a Google search!
• Although Summon and Google are good sources for pre-searching, avoid using these
sources to select your articles.
• You should search individual databases systematically to enable you to document and
describe your search in detail.
• Articles found from a Google or Summon search will still require a database search to
account for these which can be a very tricky if done back to front.
Researchers agree that the structured search approach produces the best available
evidence for informing and guiding practice (Parahoo, 1997)

6. Advanced literature search guide
Step by step guide to advanced literature searching including:
• Links to past dissertations with example literature searches
• Session presentation and video lecture
• Video search guides – database search examples
• Thesaurus – help finding search terms

8. Nursing and health databases
Specialist databases are useful for finding journal articles:
• Cinahl nursing
• British Nursing Database nursing (Proquest)
• Nursing & Allied Health nursing (Proquest)
• Medline or PubMed medical
• Psychology Database mental health (Proquest)

9. Identifying your key concepts
Identify the key concepts (main themes) in your topic or research question. Select
words or phrases that describe these.
Keep your search clean and lean. Avoid the use of vague or unnecessary words
and phases which do not relate to your key concepts e.g.
• The role of • The impact of • The link between
• Problems with • The affect on • The implications of
Tip! Use one search string per concept to avoid muddled search results

10. Identifying your key concepts
How can nurses show compassion in the care of elderly people?

11. Find alternative search terms
How can nurses show compassion in the care of elderly people?
Nurses Compassion Elderly
Nurse Empathy Elder
Health care professional Geriatric
Older
Later life

12. Example - Finding alternative search terms
For each concept try to think of as many similar or related words as possible e.g.
for diet you could also consider using any of the following:
Dietary Nutrition
Food Nourishment
Meals Eating
Malnutrition Malnourishment
Tip! Try using an online thesaurus

13. Boolean operators
Boolean operators are very useful for broadening or narrowing your search results:
OR broadens by finding any word Used within search strings
AND narrows by finding all words Used to combine search strings
Tip! It is good practice to use upper case for Boolean operators

14. Find alternative search terms
How can nurses show compassion in the care of elderly people?
s1 Nurses
s2 Compassion
s3 Elderly

15. Find alternative search terms
How can nurses show compassion in the care of elderly people?
s1 Nurses OR Health Care Professional
s2 Compassion OR empathy
s3 Elderly

16. Find alternative search terms
How can nurses show compassion in the care of elderly people?
s1 Nurses OR Health Care Professional
s2 Compassion OR empathy
s3 Elderly OR older OR later life OR Geriatric

17. Truncation
* Searches for variants of the stem (or root) of words and will increase your search
results:
Nurs* finds: Nurse, nurses, nursing
Child* finds: Child, children, childhood, childbirth
Radiograph* finds: Radiographer, radiographers, radiography
Manag* finds: Manage, manages, manager, managers, management, managing
Midwi* finds: Midwife, midwives, midwifery
TIP! Be careful not to truncate too soon e.g. leg* or comp* will retrieve too may false results

18. Apply truncation and search operators
How can nurses show compassion in the care of elderly people?
s1 Nurs*
s2 Compassion* OR empath*
s3 Elder* OR old* OR later life OR Geriatric

19. Combine search strings using AND
How can nurses show compassion in the care of elderly people?
s1 Nurs*
s2 Compassion* OR empath*
s3 Elderly OR old* OR later life OR Geriatric

20. Cinahl citation example

21. Qualitative research – how can you tell?
• It looks at people’s experiences, perceptions or attitudes – there may not be a
specific intervention.
• Research methodologies include grounded theory, ethnography,
phenomenology.
• Data collection methods include semi-structured interviews, focus groups,
narratives, diaries, observation, case studies.
• Small samples are common.

22. Quantitative research – how can you tell?
• There is a specific intervention – e.g. treatment, service, therapy, drug,
procedure.
• Research methodologies include cohort studies, RCTs, experiments.
• Data collection methods include questionnaires, observations, tests.
• Keywords such as statistics, validity, risk, ratios, sampling, scores.
• Larger samples are common.

23. Inserting a search results table
• a copy of your search results from Cinahl search history or Proquest recent
searches pages.
• This is your record of the search terms/strings you have used and the number
of results found for each.
• Manually insert a table into your word document and populate by adding in the
search words and number of results.

26. Finding full-text
• If full-text is not available try the following:

• Proquest articles - use the links to full-text
• Cut and paste the title of the article into Summon or Google
• As a last resort, you can request the article
