Two types of search strategies

Search strategy

Building blocks methodSnowball method

Postgraduate Course

Snowball method

Starting from one book or article, you search for other literature on the same topic.

Snowballing to older publications by finding out which

publications were used by the author (see bibliography of

book or article).

Snowballing to more recent publications by finding out

how often that book or article has been

cited by other authors (see Web of

Knowledge or Google Scholar).

related terms / words / subjects

narrower or broader terms

Postgraduate Course

Search in the following order

1. Thesaurus (SU)

2. Title (TI)

3. Abstract (AB)

4. Alternate spellings, synonyms

Postgraduate Course

The advantages of ‘subjects’ or

‘thesaurus terms’

One single term for variations in spelling or synonyms

(organization, organization, company, corporation)

The term is relevant (therefore, so is the article)

Automatic “Explode” function (narrower terms are

automatically included)

Extra search options (subheadings, major topics, etc.)

Subject / Thesaurus terms

Postgraduate Course

The disadvantages of ‘subjects’ or

‘thesaurus terms’

Recent articles not yet indexed

“Index errors”

Sometimes there are no suitable subjects or thesaurus

terms (new concept, specific term)

Therefore use also words

in the title or abstract!

Subject / Thesaurus terms

Postgraduate Course

Search Query

1. Search with #1 PICOC term (incl. alternative terms,

synonyms, alternate spellings, truncations, etc.) in the

thesaurus, title or abstract

2. Combine the results with OR (use the history function!)

3. Search with #2 PICOC term (incl. synonyms, etc.)

4. Combine the results with OR

5. Combine the results of step 2 and 4 with AND

Postgraduate Course

Boolean operators

AND = both terms (apples AND oranges)

OR = either one of these terms (apples OR oranges)

NOT = without this term (fruit NOT oranges)

NEAR = near this term (apples NEAR oranges)

* = replaces 0,1 or more characters (apple*= apple,

apples, applejack, applejuice, applepie, etc.)

?= replaces 1 character (organi?ation= organisation,

organization)

2. Underline the 2 to 4 most relevant keywords,

3. Start with the most relevant keyword: is it listed in the thesaurus? If not: search in the title or abstract.

4. Repeat your search with alternative terms, synonyms or alternate spellings.

5. Combine the outcome of step 4 (thesaurus), 5 (title or abstract) and 6 (alternative terms) with OR (use the history function!)

6. Repeat above steps for keyword 2

7. Combine the outcome of your search with keyword 1 and 2 with AND (use the history function!)

8. Filter the articles with “studies” (subject > studies)
