A search strategy is a set of search terms combined in such a way to maximise the number of relevant records retrieved in Library Search or a bibliographic database:
Designing a search strategy is the first step in effectively reviewing the literature in your area of interest. If you don't use the correct terms or don't combine them correctly, you will either not get enough relevant results, or you will be overwhelmed with a large number of irrelevant records.
This page will guide you through the search strategy process, allowing you to create an effective search strategy that you can use to find relevant journal articles for your topic.
Note that designing an effective search strategy can be time-consuming, so make sure you allow enough time for this part of your research!
It can be useful to write down your search topic as a question or as a search statement. This can help you identify the key concepts of your search. Eg
What are common features of Iron Age funerary rituals?
The key concepts in this example are:
Iron Age
Funerary
Rituals
You can make your search more effective by thinking of similar words which can be used to express the same concepts. For example, the concept funerary can be expressed in a variety of ways including mortuary, burial, funeral, interment etc. Be aware that academic literature sometimes uses technical terms, rather than day-to-day language. Here are some example keywords for the question above:
|
Iron Age |
Funerary |
Rituals |
|
N/A |
mortuary or burial or funeral or interment |
traditions or customs or practices or conventions |
The next step of your search strategy is to decide how best to combine your keywords. The most effective way to search databases is to use 'OR', 'AND' and 'NOT' (also referred to as Boolean Logic).
For example:
Searching for funerary OR burial OR funeral OR interment will find books or articles which include any of these words.
Searching for funerary AND rituals will find books or articles which cover both concepts.
Searching for burial NOT cremation will find books or articles which only cover burial and which specifically exclude cremation. However, it is easy to accidentally exclude relevant results which contain both terms, so please use NOT with caution.
Phrase searching: You can use double quotation marks to search for two or more words together which form a phrase eg "iron age".
Truncation: You may be able to use the asterisk (*) as a truncation command to find versions of your search terms with different endings eg searching for funer* will find books or articles on funerary, funeral, funerals etc
Brackets (parentheses): Enclosing search terms in brackets means these terms will be combined first eg "iron age" AND (funer* OR mortuary OR burial* OR interment) AND (ritual* OR tradition* OR custom* OR practice* OR convention*)
Some databases have additional search features such as proximity searching, extra character searching etc. See Database keyword search operators quick guide for more information.
Finally, you should have a look at the results of your search to see if they look useful. If your results don’t look relevant, you may need to go back to step 2 and consider if there are different words which you can use. If you aren't getting enough results, you can search for more general terms or add another keyword with OR. If you are getting too many results, you may want to consider searching for more specific terms or adding another keyword with AND. (The more terms you combine with AND, the fewer results you will get. The more terms you combine with OR, the more results you will get!)
Even if your results look relevant to the search topic, you should have a look if they meet other requirements. For example, the publication date will tell you whether a journal article is up-to-date or obsolete. Also, most databases will offer options to filter your results by other criteria. If available, it can be a good idea to filter your results to include only articles from peer-reviewed journals. This will ensure that general, non-academic sources are excluded.
If your search results are still not what you were hoping for, don’t give up! Designing a search strategy is a process and you rarely get it right first time. However, by applying these techniques, you should end up with an effective search strategy that retrieves good quality, academic information on your topic.
Subject Librarians are able to show QUB students and staff undertaking any type of literature search (e.g. literature review, scoping review, systematic review) how to:
At peak periods of demand, Subject Librarians might not be able to deliver all of the above. Please contact your Subject Librarian Carol Dunlop at c.a.dunlop@qub.ac.uk to check availability.
QUB students and staff must provide Subject Librarians with a clear search topic or question, along with a selection of appropriate keywords and synonyms. Students should discuss these with their supervisor before contacting Subject Librarians.
Subject Librarians are unable to do the following for QUB students and staff:
