{{Shortcut|[[WP:SEARCH]]}}__NOTOC__{{HelpTOC}}
This article provides an overview of Wikipedia's search feature, as well as using external search engines, such as <tt>[http://www.google.com Google]</tt>, to find information.
 
==Wikipedia search==
The searchbox provides an input field with two buttons:
* '''Go''' - the ''Go'' button (or ''Enter'' on the keyboard), will take you automatically to the best match for the entered keyword.
* '''Search''' - the ''Search'' button will return a list of matching results.
 
===Effective searching===
Here are some hints for using the native Wikipedia search feature effectively:
 
====Limiting results====
* '''Any word''': Wikipedia's default search mode will turn up results with '''''any''''' of the words in your query. For instance, <tt>[http://www.wikipedia.org/w/wiki.phtml?search=search+engine search engine]</tt> turns up many results containing only "search" but not "engine" or only "engine" but not "search" in addition to the ones you probably wanted, which contain both words.
* '''All words''': To limit to results that include '''''all''''' words, put a "+" at the beginning of each word: <tt>[http://www.wikipedia.org/w/wiki.phtml?search=%2Bsearch+%2Bengine +search +engine]</tt> returns only pages containing both words, like Google's default mode. You can also do a phrase search by enclosing words in quotes: <tt>[http://www.wikipedia.org/w/wiki.phtml?search=%22search+engine%22 "search engine"]</tt> turns up a smaller set of results, which not only have both words but have them in order.
* '''Exclude words''': To exclude results that include some words, put a "-" at the beginning: <tt>[http://www.wikipedia.org/w/wiki.phtml?search=search+-engine search -engine]</tt>
 
Boolean search is also possible, using words including "AND", "OR", and "NOT".
 
====Avoid short and common words====
If your search terms include a common "stop word" (such as "the", "one", "your", "more", "right", "while", "when", "who", "which",
"such", "every", "about") it may give a large number of non-relevant results. Historically, these words [[Wikipedia:Common words, searching for which is not possible|could not be searched]] but as of February 2006, Wikipedia's Lucene index does not use "stop words", so any word can be successfully used in seach queries.
 
====Wildcards====
You can use some limited wildcards if you really want to. Look up "[http://dev.mysql.com/doc/mysql/en/fulltext-boolean.html fulltext search]" on http://www.mysql.com/ and look down under 'boolean search' for the details. However, wildcard searches are slower, so go easy on the poor server.
 
====Words with special characters====
In a search for a word with a [[diaeresis]], such as Sint Odili&euml;nberg, it depends whether this ë is stored as one character or as "&amp;euml;". In the first case one can simply search for Odilienberg (or Odili&euml;nberg); in the second case it can only be found by searching for Odili, euml and/or nberg. This is actually a bug that should be fixed -- the entities should be folded into their raw character equivalents so all searches on them are equivalent. See also [[Wikipedia:Special characters]].
 
====Words in single quotes====
If a word appears in an article with single quotes, you can only find it if you search for the word with quotes. Since this is rarely desirable it is better to use double quotes in articles, for which this problem does not arise. See the [[wikipedia:manual of style|manual of style]] for more info.
 
An apostrophe is identical to a single quote, therefore Mu'ammar can be found searching for exactly that (and not otherwise). A word with apostrophe s is an exception in that it can be found also searching for the word without the apostrophe and the s.
 
====Namespaces searched by default====
The search only applies to the namespaces selected in the user's [[special:preferences|preferences]]. To search the other namespaces check or uncheck the tickboxes in "Search in namespaces" box found at the bottom of a search results page. Depending on the browser, a box may still be checked from a previous search, but without being effective any longer! To make sure, uncheck and recheck it.
 
Searching the image namespace means searching the image descriptions, i.e. the first parts of the image description pages.
 
====Redirects can be excluded====
Check or uncheck the tickbox "List redirects" in "Search in namespaces" box found at the bottom of a search results page.
 
====The source text is searched====
The source text (what one sees in the edit box, also called [[wiki text]]) is searched. This distinction is relevant for [[piped link]]s, for [[Wikipedia:interlanguage link]]s (to find links to Chinese articles, search for zh, not for Zhongwen), special characters (if ê is coded as &amp;ecirc; it is found searching for ecirc), etc.
 
====Delay in updating the search index====
For reasons of efficiency and priority, very recent changes are not always immediately taken into account in searchers
 
At the moment, the search engine uses an index that isn't updated at all.
 
===Multi-lingual Wikipedia search===
* You can do a multi-lingual Wikipedia search using [http://www.google.com/advanced_search?q=site:.wikipedia.org&hl=en&lr= Google Advanced Search] or entering <tt>site:.wikipedia.org</tt> in the Google search box.
* Qwika has indexes for [http://www.qwika.com English], [http://www.qwika.com/find-de German], [http://www.qwika.com/find-fr French], [http://www.qwika.com/find-jp Japanese], [http://www.qwika.com/find-it Italian], [http://www.qwika.com/find-nl Dutch], [http://www.qwika.com/find-pt Portuguese], [http://www.qwika.com/find-es Spanish], [http://www.qwika.com/find-el Greek], [http://www.qwika.com/find-ko Korean], [http://www.qwika.com/find-cn Chinese] and [http://www.qwika.com/find-ru Russian] where the original content is combined with machine translated content from/to English.
* [http://wiki.lumrix.net/en Lumrix: AJAX driven Wikipedia search engine].
 
==External search engines==
Various [[search engine]]s can provide domain-specific searches, which lets you search Wikipedia specifically. Searches are based on the text as shown by the browser, so wiki markup is irrelevant. Depending on your browser, you may also be able to use [[Wikipedia:tools|tools]] that allow you to search Wikipedia using [[bookmarklet]]s.
 
In general, external search engines are faster than a Wikipedia search. However, because the search engine's cache is based on when the site was indexed, the search may not return newly created pages. Similarly, the search engine's cached version of the page will not be as up-to-date as the link to Wikipedia itself. Also, when returning Wikipedia articles in a regular search, [[Wikipedia:mirrors and forks|mirrors and forks]] of Wikipedia content frequently rank higher than the actual Wikipedia articles because of [[search engine optimization]] techniques.
 
These issues may be less of a problem when using certain search engines that process Wikipedia differently:
 
* Yahoo! includes Wikipedia as part of its content acquisition program and gets a regular datafeed.
* Clusty downloads and processes the database regularly, generating automatic abstracts and image thumbnails and meaningfully parsing [[Wikipedia:Redirect|redirects]], [[Wikipedia:Disambig|disambiguations]], and [[Wikipedia:Category|categories]].
* Qwika only indexes wikis, and thus mirrors do not appear in their results.
 
===Google===
By following the links below, you can use the [[Google]] search engine to search Wikipedia - either all languages, or English-only. Google indexes all namespaces.
 
* [http://www.google.com/custom?domains=wikipedia.org&sitesearch=wikipedia.org Search all languages]
* [http://www.google.com/custom?domains=en.wikipedia.org&sitesearch=en.wikipedia.org Search the English Wikipedia only]
* [http://www.google.com/custom?domains=en.wikipedia.org&sitesearch=en.wikipedia.org&hq=-%22Articles+for+deletion%22 Search the English Wikipedia (excluding articles nominated for deletion)]
 
If you frequently search via Google, consider installing the [http://toolbar.google.com/ Google Toolbar]. Using the "search this site" button allows you to quickly search the English version of Wikipedia. The official Google Toolbar is for [[Internet Explorer]] ([[Microsoft Windows|Windows]] only) and for [[Mozilla Firefox|Firefox]] (works on all operating system platforms for which Firefox is available, such as Windows, [[Linux]] and [[Mac OS X]]).
 
===Yahoo!===
 
By following the links below, you can use the [[Yahoo!]] search engine to search Wikipedia - either all languages or English-only.
 
* [http://search.yahoo.com/web/advanced?vs=wikipedia.org Search all Wikipedias with Yahoo!]
* [http://search.yahoo.com/web/advanced?vs=wikipedia.org&fl=1&vl=lang_en Search English Wikipedias with Yahoo!]
 
If you frequently search via Yahoo!, consider installing the [http://toolbar.yahoo.com/ Yahoo! Companion Toolbar]. Using the "Search Only the Current Site" button allows you to quickly search the English version of Wikipedia. The official Yahoo! Companion Toolbar is only for Windows with Internet Explorer and Mozilla.
 
===Qwika===
 
Qwika is designed specifically to index wikis. Its main index is Wikipedia. It includes:
 
* all namespaces of Wikipedia
* English machine-translated into [http://www.qwika.com/find-de German], [http://www.qwika.com/find-fr French], [http://www.qwika.com/find-jp Japanese], [http://www.qwika.com/find-it Italian], [http://www.qwika.com/find-nl Dutch], [http://www.qwika.com/find-pt Portuguese], [http://www.qwika.com/find-es Spanish], [http://www.qwika.com/find-el Greek], [http://www.qwika.com/find-ko Korean], [http://www.qwika.com/find-cn Chinese] and [http://www.qwika.com/find-ru Russian].
* The above languages machine translated into [http://www.qwika.com/find English].
 
This can assist editors contributing to non-English Wikipedias by being able to search in their own language across the entire English version and then view the machine-translated version in their language.
 
* [http://www.qwika.com Qwika main page and explanation]
 
===Clusty===
 
By following the link below, you can use the [[Clusty]] search engine to search and cluster Wikipedia in English only.
 
* [http://wiki.clusty.com/ Search and Cluster English Wikipedia with Clusty]
 
If you frequently search via Clusty, consider installing the [http://clusty.com/toolbar Clusty Toolbar] (beta). Selecting the "Encyclopedia" search source allows you to quickly search the English version of Wikipedia. The Clusty Toolbar is available for [[Microsoft Windows|Windows]] with [[Internet Explorer]] and [[Mozilla Firefox]] (beta).
 
===LuMriX===
 
LuMriX is a dynamic query tool which uses lookahead to predict search terms in a list, similar to [[List of Google services and tools#Suggest|Google Suggest]].
 
By following the link below, you can use the LuMriX search engine to search different language versions of Wikipedia.
 
* [http://wiki.lumrix.net/ Search Wikipedias with LuMriX]
 
If you frequently search via LuMriX, consider installing the [http://mycroft.mozdev.org/quick/wikipedia.html LuMriX Firefox Search Plugin] (works on all operating system platforms for which Firefox is available, such as [[Microsoft Windows|Windows]], [[Linux]] and [[Mac OS X]]).
 
===Wikiwax===
 
Wikiwax is a dynamic query like LuMriX. It only searches english Wikipedia, but shows more list entries.
 
* [http://www.wikiwax.com/ WikiWax Index to Wikipedia]
 
===Other===
 
Here are more [[Wikipedia:Tools]] which make searching more convenient.
 
==Browser specific help==
===Using Mozilla to automatically search===
Listed below are ways to search Wikipedia with Mozilla-based browsers, including [[Mozilla|Mozilla Suite]], [[Mozilla Firefox]], and [[Netscape (web browser)|Netscape]] 6 and 7.
 
====Search Wikipedia from the sidebar search tab or address bar====
Works with: Mozilla Suite, Mozilla Firefox, Netscape 6/7.
 
Mozilla and Netscape 6 & 7 come with a sidebar that allows a user to search the Wikipedia site, and Firefox has a toolbar item to do the same. To install the search plugin that tells Mozilla how to search Wikipedia, do the following:
 
#Go to one of the following sources of Wikipedia search plugins. The Mycroft plugins are sometimes out of date, and plugins from the second source may work better.
##[http://mycroft.mozdev.org/quick/wikipedia.html Original search plugins from Mycroft]
##[http://carey.geek.nz/code/wikipedia-searchplugin/ Updated search plugins]
#There are versions for many languages, so pick the language local to your area.
#If [[JavaScript]] is enabled, clicking on the name of the search plugin will automatically install the search plugin.
#If you can't install the search plugin automatically, the second source above lets you right-click on the plugin and save it to disk, or download a [[ZIP file format|ZIP file]] containing all available plugins. Save the downloaded <tt>.src</tt> file in the <tt>searchplugins</tt> directory where Mozilla is installed and restart the browser to use the new plugin.
 
To make Wikipedia your default search engine in Mozilla, Beonex Communicator, and Netscape 6/7:
 
#Go to Edit, Preferences.
#Expand the Navigator tree and choose Internet Search.
#Choose Wikipedia as your default search engine.
 
With Wikipedia selected as your default engine, searches can be conducted via the search sidebar tab, search box, or the web address bar.
 
====Search Wikipedia using a bookmarklet====
Works with: Mozilla Suite, Mozilla Firefox, Netscape 6/7.
 
Wikipedia can also be searched via a bookmarklet.
 
In Mozilla Firefox, follow these steps:
 
#Right click in the search field at the top of the page, and select "Add a Keyword for this Search".
#Enter "Wikipedia Quicksearch" for the name.
#Enter "w" (without the quotes) for the keyword.
#Change the bookmark folder if you wish, and click "Add".
 
In Mozilla Suite, Netscape 6/7 and Beonex Communicator, follow these steps:
 
#Right click on the following web address and select "Bookmark this link": http://en.wikipedia.org/wiki/Special:Search?search=%s
#Go to Bookmarks, Manage Bookmarks. Choose the bookmark you have just created. Highlight the Bookmark and click Properties.
#In the dialogue that comes up, put a lowercase w in the keyword box.
#Click OK and close the properties box, then close the bookmark manager.
 
In Camino, use the Mozilla Suite directions. Use Get Info (cmd-I) in the bookmarks manager to bring up the properties dialogue.
 
To search, go to the web address bar, enter "w <i>SEARCH_QUERY</i>" (without the quotes), and press enter.
 
====Javascript in Bookmarks====
Javascript can bring additional functionality to your bookmark. The following javascript can be pasted in as the 'Location' of a new bookmark created manually, for example in the 'Manage Bookmarks' window of Firefox. If you highlight a word in a webpage then hit the new bookmark, javascript grabs the word you have selected and uses that to perform the search. If no word is highlighted, you will be prompted to enter one.
 
<nowiki>javascript:x=escape(getSelection());if(!x)%7Bvoid(x=prompt('Enter%20Word:',''))%7D;if(x)window.location='http://en.wikipedia.org/wiki/Special:Search?search='+x</nowiki>
 
The whole thing should be pasted in as a single line without spaces for it to work.
 
====K-Meleon====
[[K-Meleon]] has a search button that can be used to search Google. You can change it to search Wikipedia instead, by:
#Close K-Meleon.
#Open up <tt>prefs.js</tt> with a text editor. The file should be in your <tt>K-Meleon\Profiles\PROFILE_NAME\RANDOM_STRING.slt\</tt> directory.
#Add this line, and save <tt>prefs.js</tt>.
 
<nowiki>user_pref("kmeleon.general.searchEngine", "http://en.wikipedia.org/wiki/Special:Search?search=");</nowiki>
 
Open up K-Meleon and press the search button to search Wikipedia. To go back to Google or to use another search service, edit <tt>prefs.js</tt> and delete the added line
 
Make sure K-Meleon is closed before editing prefs.js.
 
===Advanced: Wikipedia search field for Opera browser===
 
All [[Opera (web browser)|Opera]] versions 6, 7, and 8 use a customizable text file called search.ini. This file should only be edited while Opera is not running.
The following example replaces one of the existing pre-defined [[search engine]]s. It is up to the user to avoid conflicts of shortcut key (key=). By default 'w' is taken by the download.com search, so either this or the Wikipedia one should be changed. Furthermore the 'Search Engine ##' should be replaced with a free number: '12' is free by default. The Search.ini editor makes editing trivial (see external link).
<pre>
[Search Engine ##]
Name=&amp;Wikipedia
URL=http://www.wikipedia.org/w/wiki.phtml?search=%s
Query=
Key=w
Is post=0
Has endseparator=0
Encoding=utf-8
Search Type=8
</pre>
 
====Opera 8====
Opera appears to take a copy of the "search.ini" and load it into an internal buffer of some type. After editing the file with your new entry you must change the "File Version" at the top of the file to allow for your changes to be seen in the browser.
 
=====New search buttons to drag=====
A new kind of search system has been added to Opera, which no longer requires manual editing. This will create a button on the mainbar, which can then be put anywhere you wish, even in the start panel.<br>
See http://nontroppo.org/opsed/download.php?dd=e&plugin=100&type=SE7 for a Wikipedia search button.
 
====Opera 9 (Preview)====
Just right-click on the search field you want to create a search with and click "Create search". The following dialog is really simple. You just have to select a name for the search and a search shortcut. It even alerts you if the shortcut you want is already in use.
 
====Older Versions====
Most importantly, in 7.0, you should back up your customized search.ini because the file is overwritten by the Opera installer. This is no longer true in 7.10 and later.
 
In Opera 6 and 7.0, the menu accelerator letter is defined by the &amp; in the name. In current versions the accelerator is automatically generated and may no longer be the same as the key.
 
====More information====
*[http://opera-info.xorg.pl/en/ Search.ini editing tool &mdash; makes it more easy to add search engines]
*[http://www.schrode.net/opera/search/search_ini.html How to edit Opera's search.ini] (recommended reading prior to hand-editing search.ini)
 
==Searching with TomeRaider==
After downloading the [[Wikipedia:TomeRaider database]] one can search the Wikipedia version offline. One can also search for parts of words.
 
===Searching the page history===
To search the text that appears only in the page history, you must [[special:export|export]] the text to [[XML]] format first.
 
==If you cannot find an appropriate page on Wikipedia==
If there is no appropriate page on Wikipedia, consider [[Wikipedia:How to start a page|creating a page]], since [[Welcome, newcomers|you]] can edit Wikipedia right now. Or consider adding what you were looking for to the '''[[Requested articles]]''' page. Or if you have a question, then see '''[[Wikipedia:Questions|Where to ask questions]]''', which is a list of departments where our volunteers answer questions, any question you can possibly imagine.<br>
