How to Search:
16 types of advanced search techniques
In today’s information-heavy world, knowing how to search is just as important as what you search for. While most people rely on basic keyword searches, advanced search techniques can enhance the accuracy, relevance, and reliability of your results, which are crucial for research students who require trustworthy data for papers, projects, and reports.
Whether you’re looking for information, knowledge, resources, or tools, these methods help you learn, know, create, or do something more efficiently. Mastering these eight techniques means less time scrolling, more time discovering what truly matters.
Understanding search operator
A search operator is a special symbol or command you add to your query to refine or filter search results. Instead of broad searches, operators help you find exactly what you need — such as a specific phrase, file type, or website. For example, typing site:edu limits results to educational sites, while using quotes " " searches for an exact match.
Search technique 1: Quotes “Your Query” 关键词限定
" "
When you place quotation marks around your search terms, Google will only show results containing that exact phrase in the same order. This helps filter out unrelated pages.
Example: Searching "climate change effects" will show pages with that exact phrase, not results like “effects of changing climate.”
Search technique 2: intitle: Your Query 网页标题限定
intitle:
The intitle: operator lets you find pages with your keyword appearing in the title, which usually means the page focuses on that topic.
Example: Searching intitle:RWA Tokenization shows results where “RWA Tokenization” appears in the page title.
Pro Tip: Combine intitle: + "Your Query"
This combo narrows results to pages with your exact phrase in the title, giving highly targeted outcomes. Perfect for finding focused articles or research papers.
Example: intitle:"machine learning applications" shows only pages with that exact phrase in the title.
Search technique 3: allintitle: Query 1 Query 2 限定标题多个关键词
allintitle:
The allintitle: operator finds pages with all your keywords in the title, not just one. It’s great for targeting pages that clearly focus on your full topic.
Example: allintitle:AI ethics policy shows pages with “AI,” “ethics,” and “policy” all in the title.
Search technique 4: intext: Your Query 搜索网页正文中的关键词
intext:
The intext: operator looks for pages where your keyword appears in the body text rather than just the title or URL. It’s useful for finding detailed discussions or explanations within articles.
Example: intext:"data privacy regulations" finds pages that mention this exact phrase in the content.
Pro Tip: Mix & Match various search operator
You can mix and match multiple search operators to make your search highly specific. This helps you pinpoint exactly where and how terms appear on a page.
Example: intitle:"Donald Trump" intext:"Genius Act" shows pages with “Donald Trump” in the title and “Genius Act” mentioned in the content.
Search technique 5: Using inurl: Your Query
inurl:
The inurl: operator finds pages with your keyword in the URL, often revealing site sections or topics directly related to your search.
Example: Liverpool inurl:stadiumastro intext:youtube shows pages about Liverpool on the Stadium Astro site that also mention YouTube in the content.
Search technique 6: site: Your website 限定搜索特定网站或域名
site:
The site: operator limits your search results to a specific website or domain, perfect for finding content within one source.
Example: asset tokenization site:chainup.com shows only pages from chainup.com that mention “asset tokenization.”
Another good use case for the site: operator is finding royalty-free images from websites like Pexels, Pixabay, or Freepik.
For example, if you’re looking for a cute little puppy, you can search: cute puppy site:pexels.com.
Search technique 7: Your Query imagesize:
imagesize:
The imagesize: operator lets you find images with exact dimensions, perfect for designers or anyone looking for high-quality photos (materials/ resources).
Example:
Mark Zuckerberg imagesize:2560×1440
Sam Altman imagesize:3840×2160
Elon Musk imagesize:5760×3840
2560×1440, 5760×3840, and 3840×2160 are commonly used sizes for graphic design or HD visuals.
Search technique 8: Your Query filetype:
filetype:
The filetype: operator helps you find results in a specific file format, such as PDF, PPT, JPG, PNG, SVG, GIF, or XLS — ideal for locating reports, presentations, or images.
Example: Maybank Annual Report filetype:pdf shows only PDF files of Maybank’s annual reports.
Search technique 9: Using related: — 搜索相似网站或相关内容
related:
The related: operator helps you find websites similar to a specific domain — useful for competitor research or content discovery.
Example: related:chainup.com shows other sites similar to chainup.com.
Search technique 10: Using - (Minus Sign) — 排除特定关键词或主题
- (Minus Sign)
The minus sign excludes specific words or sites from your search results, allowing you to focus on what matters.
Example: related:chainup.com -site:chainup.com shows sites related to Chainup but excludes results from chainup.com itself.
Search technique 11: Using OR / | : 搜索包含任一关键词的结果
OR / |
The OR (or |) operator lets you find pages that include either one keyword or the other, widening your search scope.
Example: AI ethics OR AI policy shows results containing either “AI ethics” or “AI policy.”
Search technique 12: Using AND — 搜索同时包含多个关键词的结果
AND
The AND operator ensures that results include all specified terms, making your search more precise.
Example: "roti canai" AND "keto friendly" shows pages that mention both phrases together.
Search technique 13: Using Asterik * — 通配符，填补缺失的词或短语
*
The asterisk acts as a wildcard to fill in missing words or phrases. It’s great for discovering variations of a search idea.
Example: best * in Paris
Google will replace the * with words like places, museums, hotels, restaurants, or tourist spots.
Search technique 14: Using stocks: — 查看公司股票与财务信息
stocks:
The stocks: operator lets you quickly check a company’s stock price and financial data.
Example: stocks:tesla
Google will display Tesla’s current stock price, market cap, price chart, and other relevant financial details.

source:
The source: operator helps you find news articles from a specific publisher in Google News.
Example: tesla source:nytimes.com
You’ll see news articles about Tesla from The New York Times.
Search technique 16: Search by Image Instead of Text
Use Google Lens (Search by image)
Google Lens lets you search the web using an image instead of text. You can upload a photo or screenshot, and Google will analyze it to identify what’s in the image or show visually similar results.
For example, you can use Google Lens to identify unfamiliar plants or landmarks, translate text within an image, or find where to buy a product.
To use Google Lens, click the camera icon in the search bar and upload your image.
How to Use Advanced Search Operators for SEO
Google search operators are useful for various SEO tasks, such as:
Building internal links & external links
Finding site indexing issues
Discovering websites for guest posting
Tracking down duplicate content issues
Track duplicate content issues
Duplicate content occurs when the same text appears on more than one web page.
It could happen on your own website — when two or more pages display identical content.
Or on someone else’s website — when another site copies your content.
Google search operators could help you identify duplicate content issues.
To check if anyone has duplicated your content, use a search like this:
-site:chainup.com "the sentence or block of text you are checking for duplicates"
-site:
-site:
Search for mentions of your brand, excluding a specific domain.
Example: "chainup" -site:chainup.com
Purpose: This helps you see how popular your brand is across the web. It’s also a great way to find link-building opportunities — a handy alternative to Google Alerts.
Pro Tip for SEO & Link Building
The asterisk * operator is especially useful for link building and content collaboration, particularly when researching listicle-style blog content.
For example, try searching: "best MPC wallets in *"
This helps your outreach or link-building team find blogs that already cover your niche — so they can reach out to the site owners to mention your brand, product, or business.
Note that many SEO experts believe listicle content is helpful for AI SEO/ GEO/ LLM SEO.
