Anthropology: Finding and using library resources: 4. How do I search effectively

Online tutorial introducing you to the skills and techniques needed for effective library research

To get the best results from online search services you need to input effective searches.  

The databases are not intelligent and will not understand your search topic. You need to devise and enter your search in a way that the databases can process to retrieve relevant search results for you.

It is useful to think of this as a three step process:

1. Identify your search terms

2. Combine your search terms

3. Use search techniques to enhance your search

Explore the guidance below on these three areas, and then complete the quiz to test your knowledge and understanding.

1. Identify your search terms

Think about your research topic/assignment and break it down into key research topics/concepts. Use those topics/concepts to produce lists of keywords that you can use for online searching.

Think carefully about suitable keywords and synonyms (alternative words that have a similar meaning) that will enable you to find manageable amounts of relevant material - not so many results that they are unmanageable and cause information overload, or so few that you retrieve insufficient information for you needs.

You may find it useful to use techniques such as brainstorming, words lists or mind maps to generate your keywords

Are there any alternative words and/or phrases you should include in your search in order to improve your search results? 

For example:
If you were researching the failure of a particular ethnographic research exercise in the UK you might use the following keywords: failure, success, demise, challenges, risk etc.

And, as well as searching for the UK, you might also search for United Kingdom, GBGreat Britain etc.

When you are searching the global literature think about differences in spellings and terminology, and incorporate alternatives into your search strategy. Truncation and wildcard symbols can help with this.

For example:   globalisation (British spelling)  vs. globalization (American English spelling) 

 

Also think about differing terminology for the same subject. Subject terms and thesauri can help you with this.

For example:  holiday vs. vacation   /      underground vs.subway      

Consider whether  your area of research uses subject specific terminology, technical terms or other controlled vocabulary.

Use these specialised terms in your searching to improve your results.

If you do not know the standard terminology then the database subject index or thesaurus may help.

Have acronyms or abbreviations been used in the sources you have read? 

These can be included in your search terms in order to find matching results. 

 

Consider whether there are  key thinkers, writers, experts or analysts who are prominent or active in your research area.

It may be worth including these 'names' in your searches. 

 

If you are searching across long time periods, remember that terminology changes over time. New words appear, others change meaning so be prepared to reflect this in your search strategy.

For example:  tweet or twitter has a dual meaning: 

  1.  posting a short message to the Twitter social media platform
  2.  bird calls or short sharp sounds

2. Combine your search terms

It is possible to use a number of different keywords or search terms in a single search, by using operators. 

Operators link your search terms and define the relationship between them.

This enables more accurate searching and therefore more relevant results being returned. It also saves you time as you don't have to carry out numerous similar searches where just one or two search terms are changed each time.

The three most commonly used operators are ANDORNOT.  These are known as Boolean operators. They can be used to broaden or narrow a search and to exclude unwanted search terms and concepts.

Use AND to narrow your search.

Using AND between your search terms narrows your search as it  instructs the database that all your search terms must appear (in any order).

For example: anthropology AND culture

                      human diversity AND culture
                      
will only return results where both words are present

Because all search terms must be present, using AND makes the search more focused. 

In some (but not all) databases and search engines the AND is implied so if you enter multiple words the database will search for results which contain all/both words.

Use OR to broaden your search.

Using OR between search terms broadens your results as any or all of your search terms can be present.

For example:   religion OR belief 
                
- will return results where either one or both of these words are present

It is extremely useful for finding synonyms or related concepts.

Using OR  enables you to carry out a number of similar searches in one go, saving you time.

Use NOT to narrow your search.

Using NOT narrows your search as it instructs the database to ignore results that contain particular words.

For example: social media NOT twitter
                      
- will return results that include social media but do not  include twitter

 

NOT  tends to be used less than the AND and OR operators. 

Use it with care as you may exclude useful articles which cover a range of topics of relevance to you.

3. Use search techniques to improve your search

You can use search techniques to help improve your searching. By applying these techniques, you can increasereduce or improve the relevancy of your search results, making it easier to access to the right materials. For more, see the Search tips guide.

Truncation is a technique that broadens your search to include various word endings and spellings.

To use truncation, enter the root of a word and put the truncation symbol at the end.

The database will return results that include any ending of that root word.

The asterisk * symbol is most commonly used for truncation. However, check out the help screens as  !, ?, or # may also be used.

For example:

global* will find global, globally, globalise, globalisation etc.

Use it with care to avoid finding too many alternatives.

Wildcards are similar to truncation but they are used to substitute for a single letter or no letter in a word.

They are useful for irregular plurals and for British/American English spellings.

They broaden your search by including variant word spellings.

The question mark symbol is most commonly used. However, check out the help screens as  ! , *, or # may also be used. 

For example:

wom?n will find woman and women

model?ing will find modeling and modelling

Phrase searching is the most limiting technique as it is used to specify that your terms must appear next to each other, and in the order you specify.

Phrase searching is commonly achieved by surrounding your phrase with quotation marks.

Always check the Database Help screens, as some databases may use different symbols.

Phrase searching examples:

"Ghetto culture"

"social practices"
