In everyday use, search engines like Google, Bing, DuckDuckGo and Yahoo accept a search term (a word), or a string of search terms, and return matching results. But most search engines are programmed to accept more advanced “filters” or “prefix operators” as well. A filter is a keyword or phrase that has particular meaning for the search engine. This includes terms like:
inurl:
intext:
site:
feed:
language:
Each filter keyword ends with a colon (:) and is followed by the relevant search term or terms - with no space before or after the colon!
Examples:
filetype:xls “house prices” AND “London”
site:nasa.gov filetype:pdf
filetype:doc “security plan” site:gov.in
