1: What do you need to know - define your question, concepts and keywords

1.1: What do you want to achieve

Thinking about why you’re looking for information and what you want to do with the answer is important as it will change how you go about searching for it. 

For example, spending a few minutes to find a specific fact is very different from planning a report or research project - as will be the audience you expect to share the results with. 

Here are some possible types of questions: 

  • Get an overview of a topic for background information
  • Find a fact or specific piece of information or the latest evidence
  • Find information to give to a patient or client / another person
  • Conduct some research
  • What sort of material am I after- case studies, systematic reviews, guidelines, patient leaflets, medicines information
  • Compare local practice with published evidence
  • Find people to learn from the experiences of others or experts

Tip:

  • Take a minute to think about the type of question you are asking and make it as clear and focused as possible
  • Write it down in a document or spreadsheet. This will be a record of your question and search strategy

1.2: Planning your search

Remember, you have to ask the right question to get the right answer! The more careful you are in wording your question, the more likely it is that your search will return results you need. 

Concepts: Start by breaking your question down into concepts or component parts

Key words: It’s important to know what you’re asking, but most of the websites you will use to search for information will work better if you describe what you want to know in a selection of key words, rather than a long sentence

See the sections below for more about ‘concepts’ and ‘keywords’.

Concepts: Think about

  • The setting, people and actions in your question
  • Need to be more specific? Use frameworks such as PICO to help you think about all aspects of your question
  • Keep in mind the purpose of your search and what you want to achieve

Keywords: Think about

  • Which words are key to each of the concepts in your question
  • Synonyms or alternative terms - words which mean nearly the same things e.g. pain vs ache
  • Stop words - like ‘the’ and ‘a’ can be removed without losing the essential concepts
  • Other spellings - especially US vs UK e.g. colour vs color

Frameworks:

  • PICO: Population, Intervention, Comparison, Outcomes
  • Helps you to think about the concepts within your question that you can use to structure your search
  • Useful for clinical questions
  • One of many - see more at Frameworks

Tip:

  • Make a table of keywords in your question with alternative terms
  • These keywords will form your search terms

1.3: Combining keywords

A lot of search engines will combine your keywords for you in the background, but using simple tricks can get you much better results whether you are using Google or a database.

Common strategies include:

Boolean operators

  • You may have encountered these before without realising what they are
  • There are three common operators: AND OR NOT
  • Usually entered in capital letters
  • Placed between your keywords, they will change the type and number of results you get

AND

  • Searches for resources containing all keywords together
  • Reduces the number of search results

OR

  • Searches for resources containing either/any keywords
  • Increases the number of results

NOT

  • Searches for resources which do not include a keyword
  • Should be used rarely and with caution as can unintentionally exclude relevant results
Boolean operators AND OR NOT Venn diagram. Key below shows: blue = results returned; white = results not returned. AND diagram shows two overlapping circles with the overlapping centre coloured blue to indicate results returned. OR diagram shows two overlapping circles with both circles completely coloured blue to indicate results returned. NOT diagram shows two overlapping circles with only the non overlapping section of left circle coloured blue to indicate results returned.

Filters

  • Menu options that allow you to add limits like date range to your search which reduces the number of results
  • Don't add too many or you'll end up with no results

Quotation marks

  • Use “” to search a phrase and return only results that include those two words together and in that order
  • For example: “social media”

Truncation

  • Use * to search singular, plural and other versions of a term
  • For example: Nurs* to find nurse, nurses, nursing

Brackets

  • Use ( ) to link concepts to find results that combine these keywords
  • For example: (nurs* AND “social media”)

Tip:

  • Many search engines and databases have help and guidance for searching
  • Include shortcuts to improve your search which can vary depending on the provider
  • When entering your search terms do this one at a time so you can see what words or terms work well
2: Where will you look - decide what sources to use

2.1: Evidence pyramid

This suggests a hierarchy of research and evidence. At the top is the highest quality of research or evidence that is robustly researched, trustworthy, unbiased and transferable. At the bottom is research or evidence that is difficult to quality assure, susceptible to bias and less likely to be easily transferable.

This can be a useful way of helping you to decide where to search and prioritise your sources. Find out more about what it is, criticisms and other approaches: Evidence pyramid explained

2.2: Select your source

The time you have spent thinking about the purpose of your search and creating your question will also help you to decide where to search. There are no hard and fast rules but the following suggestions can help you get started.

Tip:

  • Add the sources you are going to use to the table with your keywords
  • Note what happens when you search your keywords in each source
  • How many results did you get? What filters/keywords did you add or remove? What was the impact on your results?

2.3: Web and AI searching

In many cases, you will want to use formal, academic research to answer your question but sometimes a search engine is a good place to start to get an idea of the literature that might be available. However, you should take the time to reflect and assess the information you find to make sure it’s correct and will not compromise the quality of your work.

Keep in mind:

  • Many sources will not appear in search engine results and are inaccessible to AI
  • Content from some sources will be unavailable because it is behind a ‘paywall’ - this is content that you have to pay to access, usually via a subscription, such as those made available via The Knowledge Network Library Search
  • Content, conclusions and recommendations of these sources will therefore not be included in AI summaries
  • The results you see first in a search engine are largely based on whether the creators have paid to have their sites appear highest in the results rather than their relevance to your keywords
  • Most search engines have an advanced search which allows you to add multiple keywords and filters, such as Google Advanced Search
  • Google Scholar can be used to quickly search for and access journal articles. You can set it up to get easy access to online journal articles subscribed to by NHS Education for Scotland by following the steps outlines in our Google Scholar pages

3: Can you trust the information you have found - assess quality

We’ve discovered that information is available to us from lots of different sources. Now it’s time to think about how well it answers our question - is it relevant and comprehensive enough? We also need to assess the trustworthiness, particularly in the case of research or evidence. Part of figuring this out is often called ‘critical thinking’ and is a really useful skill for professional development, as well as for everyday problems.

You should consider:

  • What
  • Who
  • When

3.1: What

No matter where the information you have found has come from, there are a few things you can consider to help you evaluate and decide whether to base your decisions on it, or include it in your bibliography or project.

  • Relevancy: does the information help to answer your question?
  • Validity: are the arguments logical and has the author given evidence to support them?
  • Accuracy: is the evidence used to support the arguments relevant and correct?
  • Bias: has the author given both sides of the story or do they seem to be trying to force a particular viewpoint on the reader?
  • Evidence: how was this collected and are there references you can check? You might want to check this yourself instead of relying on the interpretation of others.

3.2: Who

Not all sources are created equal and it can be difficult to know if we can trust the information we find, particularly on the Internet. When accessing information from a trustworthy starting point, like the Knowledge Network or a library, we know that some quality checks have taken place – not so on the Internet, so here are some things to look out for to help you decide what to trust.

  • Who wrote the information? Look for an ‘About’ page or similar, which should detail who is responsible
  • Check the URL:
    • gov - government information
    • ac - academic institution (UK)
    • edu - educational institution (non-UK)
    • location e.g. ‘nz’ - New Zealand
    • https - more secure version of http usually used by public bodies
  • Are they qualified or knowledgeable enough to provide information on this subject? Look for information about the author’s educational and professional background and other publications by doing a web or library search
  • What is the aim of the website? Does it represent an organisation with particular motives or agendas? Is it trying to sell a product or promote a campaign? Look for any advertising which might provide a clue
  • Is it formal research or a personal blog or social media site? Consider how this might affect the reliability
  • It’s really easy for anyone to publish material like books and articles on the web these days, without having it checked by an editorial process. Look for logos or an ‘About Us’ page to check this
  • Has it been reviewed, who by and how well? Look for references to trustworthy sources like formal research, policy documents, legislation, etc.

3.3: When

On the Internet, there are no obligations for information to be revised or updated at any point, so it’s worth considering how up-to-date the information is.

  • Start by looking for dates the information was produced and published
  • Can you tell when it was last updated? Look for copyright information at the very bottom of the homepage
  • Use your own knowledge of the field if you can – is the information presented still useful or has it been superseded?
