New page: Google search is a free, online web search tool. ==Use Google search== ===Start Google search=== Google search is online, or Internet-based. It can be accessed at: http://www.google.co...

New page

Google search is a free, online web search tool.

==Use Google search==

===Start Google search===

Google search is online, or Internet-based. It can be accessed at:

http://www.google.com

Google search can also be accessed through a mobile phone, at:

http://m.google.com/search

Google search can also be accessed through the search bar (typically located to the right of the URL bar) on search engines such as Mozilla Firefox and Internet Explorer.

===Initiate a search query===

# Type the query you want to search in the search textbox, and press the ''Enter'' or ''Return'' key.
# Google will return a page with a ranked list of result pages (termed the ''Search Engine Rankings Page''). Each result that Googe thinks is relevant to the query is presented in the form of the page title, followed by a few lines from the page that contain the search terms, followed by the page URL.
# Visit the pages that you consider relevant. Alternatively, you may want to modify the search terms.

==Search syntax==

===Default syntax: all words treated with AND operator===

If a series of words is fed to Google search, Google by default looks for pages that have ''all'' the words, not necessarily next to each other. For instance, the search query:

<nowiki>red blue green</nowiki>

searches for pages that have all the terms ''red'', ''blue'' and ''green''. This is equivalent to the search query:

<nowiki>red+blue+green</nowiki>

Google search may ignore very common words like ''a'', ''an'', and ''it''.

The order in which terms are entered may have an effect on the order in which results are displayed. For instance:

<nowiki>red blue green</nowiki>

and:

<nowiki>red green blue</nowiki>

return results in somewhat different order.

===Phrase search using quotes===

To search for a phrase, quotes need to be put around that phrase. For instance:

<nowiki>"a bird in the hand is worth two in the bush"</nowiki>

searches for ''precisely'' that phrase. Phrase searches are case-insensitive, and Google automatically looks for conversions between whitespace and hyphenation.

===The OR operator===

To make Google search for pages that have one term ''or'' another, the syntax uses the OR operator, for instance:

<nowiki>red blue OR green</nowiki>

searches either for pages that contain the term ''red'', and in addition, contain either the term ''blue'' or the term ''green''.

===Negation===

It is also possible to make Google search for pages that do ''not'' contain a particular search term. Each search term that is to be negated should be preceded by a - sign, for instance:

<nowiki>red -blue green</nowiki>

returns pages that contain the terms ''red'' and ''green'' but do ''not'' contain the term ''blue''.

==Other operators==

===Site-specific search===

Google allows users to search only within a certain site. For this, the search query should contain:

<nowiki>site:sitename</nowiki>

The sitename should ''not'' include the http:// part. For instance, to search on the subwiki.org site, the syntax is:

<nowiki>red blue green site:subwiki.org</nowiki>

The search can also be specific to subdomains, and to directories within sites, for instance:

<nowiki>group site:groupprops.subwiki.org</nowiki>

===Wildcard search===

Google allows wildcard search, for instance:

<nowiki>"the real * is in the *"</nowiki>

This looks for phrases where the two *s could be replaced by arbitrary words (not necessarily the same word).

There is no mechanism to search for matching wildcard strings (i.e., for insisting that the wildcards at different places be the same word).

===Filetype search===

Google also allows users to specify the filetype of search results. For this, the search query should contain:

<nowiki>filetype:typename</nowiki>

For instance, to search for PDF documents on "small world":

<nowiki>"small world" filetype:pdf</nowiki>

==Other options==

Not all options used for Google search are accessible in the query box. For some options, it is necessary to go to Google's advanced search page:
