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.
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?
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.
| Concept | Why it matters | Example |
|---|---|---|
Site operator — site: restricts results to one website or domain | Cuts out unreliable noise when you only trust one source type for your investigation | apprenticeship pay site:gov.ie returns only official Irish government pages on apprenticeship pay |
Filetype operator — filetype: limits results to one file format | Official reports and datasets are often PDFs, so this finds the primary document not a news summary of it | youth employment filetype:pdf site:cso.ie finds CSO PDF reports directly |
| Exact-phrase quotes — wrapping words in " " forces an exact match | Stops the engine from scattering your words across unrelated pages | Searching "digital age of consent" Ireland keeps the phrase together |
Exclusion operator — a minus sign - in front of a word removes results containing it | Clears out a common but unwanted meaning that keeps polluting your results | apprenticeship pay -jobs drops job-advert pages so you see the pay information itself |
OR operator — the word OR in capitals returns pages matching either term | Catches both ways a topic might be worded so you don't miss good sources | apprentice OR trainee pay Ireland returns pages using either word |
| AI search prompt — a clear question you ask an AI tool, then follow up on | Good for a fast overview and for finding starting sources you then verify | Asking 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 answer | AI hallucinates confidently; an unchecked answer can be completely wrong in your KA evidence | An 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 |
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.
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.
| Issue | Solution |
|---|---|
| My operator returns no results at all | Check 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 work | OR must be in capital letters. Lowercase 'or' is treated as an ordinary word, not an operator. |
| The AI didn't give me any sources | Ask 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 open | This 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 results | Make sure you used straight double quotes " " not curly quotes. Retype the quotes directly in the search box. |
