    1 - Introduction ~5 mins

    Welcome

    Search in 2026 is really two tools sitting side by side. Traditional keyword search (Google, Bing, DuckDuckGo) hands you a ranked list of links, while AI search (Perplexity, ChatGPT search, Claude, Gemini) writes you an answer and cites its sources. Being fluent in both, and knowing when each lets you down, is exactly the skill your Module 4 investigation needs.

    By the end of this lesson, you will be able to:

    • Use traditional search operators such as site, filetype, exact-phrase, exclusion and OR to sharpen results
    • Write AI search prompts and ask the tool for its sources
    • Verify an AI answer by opening a cited source, because AI confidently invents things

    Warm-up

    Think about the last time you searched for something and got a wall of useless results. Did you change your words and try again, or did you give up? What would have helped you find the right thing faster?

    2 - Key Concepts ~8 mins

    Today's lesson works in two worlds. Traditional search rewards precise keywords and operators; AI search rewards clear questions and follow-ups. The one rule that spans both: you own the truth of your findings, so anything an AI tells you must be checked against a source you can open.

    ConceptWhy it mattersExample
    Site operatorsite: restricts results to one website or domainCuts out unreliable noise when you only trust one source type for your investigationapprenticeship pay site:gov.ie returns only official Irish government pages on apprenticeship pay
    Filetype operatorfiletype: limits results to one file formatOfficial reports and datasets are often PDFs, so this finds the primary document not a news summary of ityouth employment filetype:pdf site:cso.ie finds CSO PDF reports directly
    Exact-phrase quotes — wrapping words in " " forces an exact matchStops the engine from scattering your words across unrelated pagesSearching "digital age of consent" Ireland keeps the phrase together
    Exclusion operator — a minus sign - in front of a word removes results containing itClears out a common but unwanted meaning that keeps polluting your resultsapprenticeship pay -jobs drops job-advert pages so you see the pay information itself
    OR operator — the word OR in capitals returns pages matching either termCatches both ways a topic might be worded so you don't miss good sourcesapprentice OR trainee pay Ireland returns pages using either word
    AI search prompt — a clear question you ask an AI tool, then follow up onGood for a fast overview and for finding starting sources you then verifyAsking Perplexity "What is the standard VAT rate in Ireland and give me your sources" returns an answer plus links to check
    Verification — opening at least one cited source before trusting an AI answerAI hallucinates confidently; an unchecked answer can be completely wrong in your KA evidenceAn AI names a statistic; you open its cited link and find the figure is actually different — you catch the error before it reaches your investigation

    Using an AI tool for search

    For search you use the AI as an Explainer: you ask it to explain a topic and point you at sources you can open and check for yourself.

    3 - Step-by-step Task ~20 mins

    Work through a short comparison: run the same information need several ways using traditional operators, then run it through an AI search tool and check its sources. You'll build your reusable cheatsheet as you go. If you haven't picked your investigation topic yet, use apprenticeship pay in Ireland for this task.

    4 - Common Issues ~3 mins

    Common Issues

    IssueSolution
    My operator returns no results at allCheck there is no space after the colon — it must be {{code:site:gov.ie}} not {{code:site: gov.ie}}. Also try a broader domain like .ie if the specific site has nothing.
    My OR operator didn't workOR must be in capital letters. Lowercase 'or' is treated as an ordinary word, not an operator.
    The AI didn't give me any sourcesAsk again and explicitly add "list your sources with links". Some tools only cite when you ask directly. If it still won't, treat everything it says as unverified.
    The link the AI cited doesn't exist or won't openThis is a hallucinated source. Do not use the AI's claim. Search the fact yourself using traditional operators to find a real source.
    My exact-phrase quotes still return loose resultsMake sure you used straight double quotes " " not curly quotes. Retype the quotes directly in the search box.

    5 - Portfolio Build ~12 mins

    Independent Practice

    Your goal: Finish a reusable Search Cheatsheet for your Something Real investigation so you can find reliable sources fast and never get caught out by an unchecked AI claim.
    Time:~15 minutes
    Task: Open the {{code:101_search_cheatsheet_v1.docx}} file you started in the step-by-step task, inside the {{code:sm4}} sub-folder of your Project Portfolio. Finish the operator table with at least three of the operators you learned, each with a real example built from your own investigation topic. Then add two AI search prompts for the same topic, and for each one write a single line saying whether the AI's answer held up when you opened a cited source. If you have time, add the remaining operators and a third AI prompt as bonus rows.
    Success criteria:
    • At least three operators are listed, each with a real example built from your own investigation topic
    • Two AI prompts are written for the same topic, each with a one-line verification note
    • At least one verification note honestly records whether the AI matched its source or not
    • The cheatsheet is saved as {{code:101_search_cheatsheet_v1.docx}} inside your {{code:sm4}} folder and is easy to scan
