Refine web searches
You can use symbols or words in your search to make your search results more precise.

Google Search usually ignores punctuation that isn’t part of a search operator.
Don’t put spaces between the symbol or word and your search term. A search for site:nytimes.com will work, but site: nytimes.com won’t.
Common search techniques

Search for an exact match
Put a word or phrase inside quotes. For example, "tallest building".

Search for wildcards or unknown words
Put a * in your word or phrase where you want to leave a placeholder. For example, "largest * in the world".

Combine searches
Put "OR" between each search query. For example, marathon OR race.

Search for a specific site
Put "site:" in front of a site or domain. For example, site:youtube.com or site:.gov.

Search for related sites
Put "related:" in front of a web address you already know. For example, related:time.com.

See Google’s cached version of a site
Put "cache:" in front of the site address.
