The webpages maintained by the Google Help Center have text describing more than 15 various search options. The Google operator
OR– Search for either one, such as “price high OR low” searches for “price high” or “price low”.
-(minus sign) – Exclude a word or a phrase, such as “apple -tree” searches where word “tree” is not used.
""– Force inclusion of a word or a phrase (Note that the original
+operator was removed on October 19, 2011).
*– Wildcard operator to match any words between other specific words, e.g. “type * blood”.
..– Range operator, e.g. “$50..$100”.
Some of the query options are as follows:
define:– The query prefix “define:” will provide a definition of the words listed after it.
stocks:– After “stocks:” the query terms are treated as stock ticker symbols for lookup.
site:– Restrict the results to those websites in the given domain, such as,
site:www.acmeacme.com. The option “site:com” will search all domain URLs named with “.com” (no space after “site:”).
intext:– Prefix to search in a webpage text, such as “intext:google search” will list pages with word “google” in the text of the page, and word “search” anywhere (no space after “intext:”).
allintitle:– Only the page titles are searched (not the remaining text on each webpage).
intitle:– Prefix to search in a webpage title, such as “intitle:google search” will list pages with word “google” in title, and word “search” anywhere (no space after “intitle:”).
allinurl:– Only the page URL address lines are searched (not the text inside each webpage).
inurl:– Prefix for each word to be found in the URL; others words are matched anywhere, such as “inurl:acme search” matches “acme” in a URL, but matches “search” anywhere (no space after “inurl:”).
The page-display options (or query types) are:
cache:– Highlights the search-words within the cached document, such as “cache:www.google.com xxx” shows cached content with word “xxx” highlighted.
link:– The prefix “link:” will list webpages that have links to the specified webpage, such as “link:www.google.com” lists webpages linking to the Google homepage.
related:– The prefix “related:” will list webpages that are “similar” to a specified web page.
info:– The prefix “info:” will display some background information about one specified webpage, such as, info:www.google.com. Typically, the info is the first text (160 bytes, about 23 words) contained in the page, displayed in the style of a results entry (for just the 1 page as matching the search).
filetype:– results will only show files of the desired type (e.g. filetype:pdf will return pdf files)
