Effective Searching: Part 3 - Narrow your search (Web Version)
- 1. Effective Search Strategies for Researchers -3 Academic Liaison Librarian (Research) Contact details
- 3. Effective Searching Define your information need • What types of resource do you need? • Identify where to search. • Identify your key concepts. Broaden your search • Be compre- hensive. • Ensure nothing is missed un- necessarily. • “Cast your nets wide.” Narrow your search • Be focused. • Exclude any ‘noise’. • Ensure you can use your reading time most efficiently. • “Use the right nets.” Evaluate your results • Identify gaps. • Assess un- expected results. • Review search terms with new knowl- edge. Make your results work for you • Be efficient with your time. • Search alerts. • Citation searching.
- 4. Narrow your search (1) Focussing your search a) Combining your search concepts (AND connector / proximity connectors) b) Phrase searching (2) Filtering your search a) Excluding results (NOT connector) b) Searching in facets
- 5. Combining search terms 1:
- 6. (a) Combining search concepts Using the AND connector will return only those results which include both the term copyright and the term photograph. AND Narrow your search
- 7. (a) Combining search concepts Some services will assume an AND between two terms even if you don’t include it… … but not all. AND Narrow your search e.g.
- 8. (a) Combining search concepts Examples include: AND Narrow your search Power Search: Requires use of ‘AND’ connector. If not included, searches for terms appearing as a phrase or where two terms appear consecutively. Including the ‘AND’ connector “combines search terms so that each search result contains all of the terms”. Not including runs a search against an account default setting (At Durham, this is “appearing within 5 words of”) http://support.ebsco.com.ezphost.dur.ac.uk/help/index.php?help_id=35
- 9. (a) Combining search concepts So you may want to get into the habit of using it even when not necessary… 1. Avoid mistakes 2. Make cutting & pasting your search between databases easier. Narrow your search
- 10. Combining search terms 2:
- 11. b) Combining search concepts: multiple synonyms (teen OR adolescent) AND (attainment OR achievement) AND Combining search terms 2: AND teen OR adolescent attainment OR achievement
- 12. Combining search terms 3:
- 13. c) Proximity connectors truth AND reconciliation Will return results where both terms appear… Combining search terms 3:
- 14. c) Proximity connectors truth AND reconciliation Will return results where both terms appear… Anywhere within the document. Combining search terms 3:
- 15. c) Proximity connectors truth AND reconciliation Will return results where both terms appear… Anywhere within the document. They could appear several pages apart and be unrelated. Combining search terms 3:
- 16. c) Proximity connectors truth AND reconciliation To account for this, some databases will allow you to use a proximity connector instead of AND. This will only return results where one keyword appears within # words of another keyword. Combining search terms 3:
- 17. c) Proximity connectors truth w/3 reconciliation Combining search terms 3: WITHIN 3 WORDS – WILL BE INCLUDED MORE THAN 3 WORDS – WOULD NOT BE INCLUDED
- 18. (b) Proximity connectors Combining search terms 3: STOP WORDS USUALLY IGNORED (BUT NOT ALWAYS – BE AWARE)!
- 19. Truth w/5 reconciliationTruth /5 reconciliation Truth N5 reconciliation Truth adj5 reconciliation Combining search terms 3: Truth NEAR/5 reconciliation NOTE – DIFFERENT DATABASES WILL USE DIFFERENT SYMBOLS FOR PROXIMITY CONNECTORS. EXAMPLES INCLUDE: All of the above could be used for a similar purpose: • Finding results where ‘truth’ appeared within 5 words of ‘reconciliation. But some databases might use ‘N5’ to achieve this where another database might use ‘w/5’ or ‘adj5’.
- 20. Combining search terms 3: Some databases (such as JSTOR) use proximity connectors differently – and this can impact on how you run more complex searches. “A search for debt forgiveness~10 will give you results that include both the words "debt" and "forgiveness" within 10 words of each other.” https://support.jstor.org/hc/en-us/articles/115012261448-Searching-Truncation-Wildcards-and-Proximity This can mean some searches won’t work. For example, if you need to search for a phrase (e.g. “duty of care”) in proximity to another term (e.g. ‘snail’).
- 21. Phrase searching
- 22. “Truth and Reconciliation Commission” To search for only results which include a specific phrase. Can be useful for: • Commonly used names of people, organisations, events of terminology/methodology. • E.g. “duty of care”, “Guardian Newspaper”, “Foreign Office” Phrase searching
- 23. “ Truth and Reconciliation Commission” Phrase searching
- 24. {Truth and Reconciliation Commission} Phrase searching … does it differently
- 25. {Truth and Reconciliation Commission} Exact phrase Phrase searching … does it differently
- 26. {Truth and Reconciliation Commission} “Truth and Reconciliation Commission” Exact phrase Approximate or ‘loose’ phrase Phrase searching … does it differently
- 27. Excluding terms
- 28. “Truth and Reconciliation Commission” NOT “South Africa” Will return results where the phrase “Truth and Reconciliation Commission” appears, but exclude those results which also include the term “South Africa”… Excluding terms
- 29. “Truth and Reconciliation Commission” NOT “South Africa” … but be careful with the NOT connector. It might exclude results which offer a comparison, or results where the excluded term appears only in a reference or footnote, which may still be of interest. Excluding terms
- 31. • In addition to narrowing your search by choice of keywords and connectors… • Consider carefully where you search for terms appearing within a document. • Use the filters provided, or search in particular fields (title, subject, abstract) • If you only search for results where your most important terms appear in the title or abstract, you will likely have fewer results to evaluate and they should be more relevant. Searching within facets
- 34. • Narrowing your search - Summary – Focussing copyright AND photographs – Proximity searching negligen* w/5 PwC – Phrase searching “duty of care” – Excluding terms property NOT intellectual – Phrase searching “duty of care” – Faceted searching Terminology and symbols vary, depending on which database or catalogue you are using Narrow your search

Hinweis der Redaktion
- This is about you controlling the context in which search results are included, and identifying and excluding those results which are ‘odd one’s out’ – they mention the search terms you have chosen, but they don’t fit in with the overall pattern or topic you are interested in sufficiently enough to warrant your time and effort.
- Be aware of some differences or additional features in specific databases
- Be aware of some differences or additional features in specific databases

- Do not dwell on this.. An important (and perhaps obvious) part of the process, but one that may not be an obvious or easy answer initially – you often have to search first in different places to see what gives the best range of results… and then from your results list see what subject terms or filters are offered based on those results.
- As postgraduate researchers, there is not just a pressure to “find some stuff”… but you will feel you are expected to have found and read everything which is of relevance to your topic of research, and read around the edges to clearly define your topic. Reading everything is, of course, an impossible task. So what you actually need to have is the confidence, (for meetings with supervisors, conference papers you deliver, articles your write… and then your final completed thesis, your viva and any subsequent direction your career takes you…) the confidence that you have found (and read) everything of importance, and an ability to articulate and demonstrate why you are confident you have searched for that information effectively. DEFINE - This has two motivations: In terms of form, you must search in the most appropriate places, having decided the type and amount of information you want based upon your information need In terms of subject, you are also defining your boundaries. It is likely that for any extended piece of research you are going to have multiple ‘contexts’ and ‘avenues’ to explore – and there may be other linked areas you are not interested in. Having a broad understanding of the topic may also help inform your choice of search term, as well as helping you identify those areas you wish to exclude from your search. BROADEN Metaphor – cast your net wide to make sure you can capture as much as possible that ‘might’ be relevant, and ensuring you aren’t missing anything which might potentially be useful. - this is about being comprehensive, rather than focussing to precisely to start with. This is about ensuring you don’t inadvertently miss anything. NARROW Metaphor: ensuring you are using the right nets for the job to allow those results you don’t want to slip through the holes, and those you are to be pulled onto your deck. - once you have ensured your search can be as comprehensive as possible, you then need to make sure you focus it to help filter out the ‘noise’ and to just return the most relevant results. This is about ensuring you use your reading time most efficiently. EVALUATE This is not about critically evaluating the content and conclusions of the articles. This is about evaluating your results as a whole to identify problems with your search, or improvements you could make. - rarely will you find all the most relevant and appropriate results in your first search. Using the results you do find to identify:- Key authors, or opposing arguments, to explore further Alternative and additional search terms Specific topics you might want to focus on New avenues of research topic or methodology WORK FOR YOU Finally, this is about using those key sources you locate to work for you:- - providing you with a rich source of pre-selected earlier research from their own list of references - citation searching to see how the ideas and research in the key sources you have identified have been taken and developed further
