Philosophy: Search Strategies

What is a Search Strategy?

A search strategy is a structured plan for finding information on a specific topic. It involves analysing your topic, identifying key concepts, selecting appropriate keywords, and applying techniques such as Boolean operators, wildcards, and truncation. A well-planned strategy saves time, improves accuracy, and ensures you retrieve the most relevant and comprehensive results.

How to Formulate a Search Strategy

1. Do Background Reading

Begin by reading general or introductory material to understand your topic, spot key issues, and identify important terminology. This will help refine your research focus and guide your choice of search terms.

2. Define and Analyse Concepts

Break your topic into main concepts by:

  • Identifying key nouns and verbs (e.g., impact, policy, education).
  • Asking the who, what, where, when, and why of your topic.
  • Reformulating your topic into different questions or statements to reveal alternative keywords.

3. Develop Search Terms and Techniques

Search Terms & Synonyms

  • List main keywords and include synonyms or related terms (use a dictionary, thesaurus, or database thesauri).

  • Consider British vs. American spelling (e.g., globalisation vs. globalization).

  • Use controlled vocabulary such as subject headings in library catalogues or database thesauri.

  • Think in hierarchies:

    • Broader terms – e.g., national symbols when searching for flags.

    • Narrower terms – e.g., flags or anthems when searching for national symbols.

  • Include jargon in the field and plain-language equivalents, as terminology may evolve.

  • Add a specific subject or context keyword if you need to narrow your results.

Boolean Operators

  • AND – narrows the search (e.g., education AND technology).

  • OR – broadens the search by including synonyms (e.g., teenagers OR adolescents).

  • NOT – excludes terms (e.g., bats NOT cricket).

  • Most databases offer Advanced Search options where rows can be linked by AND/OR/NOT (default is AND).

Wildcards and Truncation

  • Asterisk (*) – retrieves variant endings (educat* → education, educating, educator).

  • Question mark (?) – replaces a single character (globali?ation → globalisation, globalization).

  • Quotation marks (" ") – search for an exact phrase ("South Africa").

  • Example: “south* Africa*” → southern Africa, southern African, South Africans, etc.
