Google Search Operators Reference

Documentation on Google search operators for advanced searching and filtering of results.

Practical understanding of every Google search operator that still works, along with some advice on how to use them.

How Google Interprets Queries

Before diving into operators, you need to know how Google reads your searches.

Parentheses

Parentheses don’t work the way most people think. If you search for [ (A B) OR (C D) ] to get results containing either “A B” or “C D”. Google doesn’t support it. The parentheses are ignored, which means you’re actually searching for [ A B OR C D ], returning results with just A and either B or C and D. If you need to search multiple phrase combinations, you have to run separate searches and combine results yourself. Most people get this wrong.

Word Order

Word order matters. The query [ to be or not to be ] returns very different results than [ be to not or be to ]. Google uses word order as a ranking signal, so always consider phrasing when conducting research.

Google Search Operators Reference

Operator Syntax Example Description Status
site: penguins site:aq
accidents site:bls.gov		 Restricts results to specific domain or subdomain. Works with or without periods (.gov or gov). Essential for competitive analysis. Active
-site: site:nyc.gov -site:www.nyc.gov Excludes specific domain from results. Useful for finding subdomains or excluding sites like Wikipedia. Active
– (minus) jaguar -cars -football -os
anti-virus -software		 Excludes terms from results. Must immediately precede word with space before it. Can exclude multiple terms or entire sites. Active
“phrase” "Alexander Bell" Forces exact phrase matching. Use sparingly as it may exclude good results with slight variations. Active
“word” "ca" history Forces exact word match without synonym expansion. Use when Google is being too helpful with synonyms. Active
OR mesothelioma OR "lung disease" treatment Specifies alternatives. Must be uppercase. Returns results matching either term. Active
***** (wildcard in URL) site:www.*creative.com Matches any token in URL. Token = complete term without spaces. Matches prefix strings before tokens except TLDs. Active
***** (wildcard in phrase) "whenever * says * whenever" Fill-in-the-blank search within quotes. Google finds best matches for that position (up to 5 terms). Dramatically more effective than searching without. Active

Common Uses

Understanding how to use advanced Google search operators and queries may seem old school, but it can be very powerful. For example, you can adjust drastically improve the quality of output in Gemini or Claude research tasks.

That said, there are definitely some common uses I typically repeat myself and I suspect many others do too. Here are just a few real-world use cases:
