Advanced search —
finding what you need

A basic Google search returns billions of results. Advanced operators let you cut through the noise to find exactly what you are looking for — in seconds.

01"Exact phrase" — quotation marksMost useful
Wrapping words in quotes tells the search engine to find that exact sequence of words. Use it when you know the precise phrase — a title, a quote, a technical term.
"climate change policy India""machine learning in healthcare""annual report 2024"
02site: — search within one websiteVery powerful
The site: operator restricts your search to a single domain. Use site:gov.in to search all Indian government websites, or site:edu to search academic institutions.
site:gov.in budget 2024site:bbc.com Indiasite:edu machine learning
03- (minus) — exclude a wordFilter noise
Place a minus sign directly before a word (no space) to exclude pages containing it. Essential when a search term has multiple meanings.
jaguar -car -footballpython -snake -montymercury -planet -car
04filetype: — find specific file formatsFor documents
Find PDFs, Word documents, Excel files, or PowerPoints directly. Invaluable for finding official reports, academic papers, and government data.
filetype:pdf annual report RBIfiletype:xlsx India GDP datafiletype:ppt climate change
05OR — find either termBroaden search
OR (must be capitalised) lets you search for pages containing either term. Useful when a topic has multiple names or synonyms.
heart attack OR cardiac arrestsmartphone OR mobile phoneAI OR "artificial intelligence"
06before: and after: — date rangeTime filter
Filter results to a specific time window. Use after:2023-01-01 to find only recent results, or combine both for a period.
AI regulation after:2023-01-01budget India after:2024-01-01COVID before:2021-06-01 after:2020-01-01
07intitle: and inurl: — search page structureAdvanced
intitle: finds pages with your word in the title — a strong indicator the page is specifically about that topic. inurl: finds pages where your word appears in the URL.
intitle:"climate policy" Indiainurl:blog machine learningintitle:tutorial Python beginners
Search strategy — good habits vs common mistakes
✓ Good search habits
  • Start broad, then add operators to narrow
  • Use specific technical vocabulary
  • Try 3–5 different phrasings of the same question
  • Search in English for more academic results
  • Use date filters for time-sensitive topics
  • Check page 2 and beyond — good results are often buried
✗ Common mistakes
  • Typing full questions ("What is the best…")
  • Only clicking the first result
  • Ignoring the date of a result
  • Trusting ad results as authoritative sources
  • Not checking the domain for credibility
  • Giving up after one search attempt

How to research
a topic properly

Research is a skill. Finding one article is not research. Here is a repeatable 7-step process used by journalists, academics, and analysts.

"Research is to see what everybody else has seen, and to think what nobody else has thought."
— Albert Szent-Györgyi, Nobel laureate
Primary vs secondary vs tertiary sources
Primary sources
Original evidence
Created at the time of the event or study. Government reports, scientific studies, interviews, legal documents, photographs.
Secondary sources
Analysis of primary
Written after the fact, analysing primary sources. Textbooks, news articles, review papers, biographies.
Tertiary sources
Summaries of both
Wikipedia, encyclopaedias, databases. Good for orientation — poor for citation.
The golden rule: Always try to find and cite the primary source. If a news article says "a study found X", find the actual study. The article may have misread or sensationalised the finding.

Evaluating sources —
bias, fairness & credibility

Not all information is equal. Learning to evaluate the credibility and bias of a source is one of the most important skills of the 21st century.

Two evaluation frameworks — click a letter to explore
Understanding media bias

All media has some degree of bias. Being aware of where a source sits on the political spectrum helps you read its output critically. No outlet is perfectly neutral.

Far LeftLeftCentre-leftCentreCentre-rightRightFar Right
Bias does not equal wrong. A source can be biased and still report factually. A source can appear neutral and still mislead through selective omission. What matters is whether claims are evidence-based and transparent about perspective.
Source credibility tiers
Tier 1 — High credibility
Peer-reviewed journals
Expert-reviewed before publication. Retraction policy. Methodology disclosed.
Tier 1 — High credibility
Official government data
Primary source. Census, official statistics, legislation, court records.
Tier 2 — Generally reliable
Established news outlets
Editorial standards, named journalists, corrections policy. Still carries bias.
Tier 2 — Generally reliable
Reputable NGOs / think tanks
Transparent funding, named researchers. Check funder agenda.
Tier 3 — Verify carefully
Wikipedia
Good overview. Follow footnotes to primary sources. Never cite Wikipedia itself.
Tier 3 — Verify carefully
Opinion / commentary sites
Useful for understanding a perspective — not as evidence.
Tier 4 — Treat with scepticism
Anonymous / unattributed sites
No author, no date, no About page. No accountability.
Tier 4 — Treat with scepticism
Social media posts
No editorial process. Virality is not a credibility signal.
Source credibility checklist — tick ✓ yes / ✗ no for any source you are evaluating

Avoiding traps —
disinformation & scams

Disinformation is designed to exploit your psychology — urgency, fear, outrage, and greed. Understanding how it works is the first step to not falling for it.

The uncomfortable truth: Research shows that false news spreads 6× faster than true news on social media (MIT, 2018). This is not because people are unintelligent — it is because disinformation is engineered by professionals to be compelling and shareable. Awareness is your best defence.

These are realistic examples of scams and disinformation. Click each one to see the red flags. One example is actually trustworthy — can you identify it before clicking?

Universal red flags — if you see these, pause and verify
Language red flags
⚑ “BREAKING” or “URGENT” for old or unverified news
⚑ Excessive CAPITALISATION and exclamation marks!!!
⚑ “Share before they delete this!”
⚑ “They don’t want you to know this”
⚑ Strong emotional outrage with no evidence cited
Source red flags
⚑ No author named, no date, no About page
⚑ Domain mimics a real site (bbc-news.net, sbi-verify.com)
⚑ Only one website is reporting this “huge” story
⚑ Extraordinary claim with no extraordinary evidence
⚑ Requests money, personal info, or passwords

Reverse image search: If a photo looks suspicious, right-click it and choose “Search image with Google” (or use TinEye.com). You can often find the original context — many viral “current event” photos are actually years old or from a different country entirely.

Citing sources
& intellectual property

Citing sources is not a bureaucratic formality — it is how you give credit, allow verification, and participate honestly in the exchange of knowledge.

Why citing sources matters
Give credit
The person who did the work deserves recognition. Using their ideas without acknowledgement is intellectual theft.
Enable verification
Citations allow readers to check your claims, read more, and verify that you represented the source correctly.
Build credibility
A well-cited argument is far more persuasive. It shows you have engaged with evidence rather than just asserting.

For education / commentary / review — Likely fair use. Keep it short. Always credit the source. Do not use for commercial purposes.
Quoting in an essay — Generally fine with citation. Keep quotes short — use only what you need. Paraphrase the rest.
Copying an entire article, song, or book — No. Copyright infringement. Paraphrase and cite instead.
Using a photo found on Google Images commercially — No. Search for Creative Commons licensed images on Unsplash, Pexels, or Wikimedia Commons instead.
