Tips on Improving Search and Research Skills

• Online search and research are more than just typing a word into a search box.

  • It is a skill that requires technique to get better results.
  • The guide below provides steps to improve search quality and relevance.

• 1. Narrow your topic

  • Identify key concepts or important ideas in the question.
  • Example question (paraphrased): "What precautionary measures should you observe when you are logged in to a public computer?"
  • Do not type the entire question verbatim in the search box, as this can yield many inappropriate results.

• 2. Identify keywords

  • From the question, the keywords are: $ext{precautionary measures, observed, logged-in, public computer}$
  • Keywords are the terms that search engines use to locate related documents.

• 3. Build a basic search string using AND

  • Place the word "AND" between each keyword to narrow results.
  • Example search string: $ext{Precautionary measures AND observe AND logged-in AND public computer}$
  • Result: typically fewer, more relevant results.

• 4. Identify synonyms and use OR for broader relevance

  • Not all sources use identical terminology; grouping synonyms expands search without losing relevance.
  • Common synonyms from the example: Precautionary measures ⇄ preventive measures; Observe ⇄ pay attention to; Logged-in ⇄ Signed-in.
  • Example expanded search: $ext{Precautionary measures OR preventive measures AND observe OR pay attention to AND logged-in OR signed-in AND public computer}$

• 5. Review initial results and refine keywords

  • If first pages aren’t helpful, adjust keywords.
  • Possible refinement: remove the phrase "pay attention to" and use:
  • Example refined search: $ext{Precautionary measures OR preventive measures AND observe AND logged-on OR signed-in AND public computer}$
  • If still not satisfactory, continue refining until results align with the need.

• 6. Use the plus (+) sign for required terms

  • Place a plus sign before a keyword to require its presence in results.
  • Example: $+ ext{preventive measures}$

• 7. Use the minus (-) sign to exclude terms

  • Place a minus sign before a word to exclude it from results (no space after minus).
  • Example: $ext{public computers} - ext{personal}$

• 8. Use wildcards for variations

  • Wildcard characters (*) find morphological variations of a root word.
  • Example: $ext{measur*}$ finds measure, measures, measuring, etc.

• 9. Use quotation marks to search exact phrases

  • Enclose exact phrases or proper names in quotation marks.
  • Example: $ext{"precautionary measures"}$
• 10. Use several search engines
  • Rely on multiple search engines to diversify results.
  • Major search engines include Google, Yahoo (which uses Google), AltaVista, Bing, Lycos.

How to Evaluate Websites

• Purpose of evaluation

  • To determine credibility and reliability of web resources used for research.

• 1. Domain type and structure

  • Consider the domain type as a quick credibility signal.
  • Domain components:
  • Subdomain or third-level domain (e.g., www)
  • Second-Level Domain (SLD) – name of the site
  • Top-Level Domain (TLD) (e.g., .com, .edu, .org, .gov, .net, .mil)
  • If the site is personal, apply deeper evaluation beyond domain type.

• Preferred domain types and meanings

  • .com → Commercial
  • .edu → Educational
  • .org → Organizational
  • .gov → Government
  • .net → Network
  • .mil → Military

• 2. Author and publisher credentials

  • Check if the author’s credentials or affiliations are listed to assess qualifications.
  • Check the publisher as well.
  • Look for contact information (email, address, phone).

• 3. Purpose and objectivity of the document

  • Determine why the document was produced and its purpose.
  • The document should provide accurate information and be objective.
  • Some sites may have a promotional bias (e.g., to sell products).
  • Bias isn’t inherently bad but requires investigation of authors or connections to assess influence.

• 4. Publication date and updates

  • Check when the document was published and when it was last updated.
  • Freshness depends on topic needs: some topics require current info; others tolerate older sources.
  • Verify that links are current and that there are no dead links.

• Practical implications

  • Credible sourcing supports informed decision-making and ethical information use.
  • Bias awareness helps avoid manipulation and promotes critical thinking.

Key Concepts and Connections

• Information literacy framework

  • Ability to identify, evaluate, and use information effectively and ethically.
  • Includes recognizing information quality, credibility, and relevance.

• Cybersecurity and privacy implications

  • Understanding how search strategies can reduce exposure to unreliable sources and phishing risks.
  • Being mindful of where and how information is sourced and shared online.

• Real-world relevance

  • In academic research, journalism, policy, and everyday information consumption, structured search techniques lead to better, faster, and more trustworthy results.

• Foundational skills that underpin these notes

  • Critical thinking, source evaluation, and evidence-based reasoning.
  • Ethical considerations in using and citing online information.

• Quick reference checklist derived from the module

  • Assess information quality, source credibility, author qualifications, and potential biases
  • Verify publication date and link validity
  • Use AND/OR logic, synonyms, and operators (+, -, *, quotes) to refine searches
  • Cross-check results across multiple search engines
  • Always consider domain type and purpose when evaluating a site

Examples of practical application

• When researching online safety on public computers, use targeted keywords and operators to filter noise, then verify sources with reputable domains and author credentials.
• Prioritize sources with clear publication/update histories and avoid sites with dead links or unclear authorship.

Note on formulas and notation used in search strings

• Example search string (AND):
  $ext{Precautionary measures AND observe AND logged-in AND public computer}$

• Example search string (OR for synonyms):
  $ext{Precautionary measures OR preventive measures AND observe OR pay attention to AND logged-in OR signed-in AND public computer}$

• Example requiring a term: $+ ext{preventive measures}$

• Example excluding a term: $ext{public computers} - ext{personal}$

• Example wildcard: $ext{measur*}$

• Example exact phrase: $ext{"precautionary measures"}$

• These techniques collectively help in crafting precise queries, expanding relevant results when needed, and filtering out irrelevant or biased information.
