Searching Wikipedia
Wikipedia search can be accessed in the "search" box at the left side of a Wikipedia window and also by using the "Search" special page.
Wikipedia searchType your keywords in the box to the left under "search" and then click:
In addition to the Wikipedia search results, a box on the right shows the most relevant results from our sister projects, such as Wikitionary, Wikisource and Wikibooks. Go button
Specialized uses of the Go button include the following:
Tips for effective searchesPhrases in double quotesA phrase can be found by enclosing it in double quotes. For example, "holly dolly" returns six matches; holly dolly (two standalone words) returns more than 200. Boolean searchingBy default logical AND is applied to all search terms, just as on all major search engines. One can also exclude terms with -, e.g. windows -system, or force OR boolean operation like this windows OR system (note the uppercase OR). Additional featuresThe following features can be used to refine searches:
DisambiguationYou may type in something like Plaque, that takes you to a list of the many things you could mean by it. This is called a disambiguation page, and it's there to make things easier for you. If it wasn't for that, you'd have to read our minds and know exactly what multiword code we'd thought of for each one. RedirectionSome things can be called by many names. The Flag of the United States, for instance, could be called the American Flag, the US Flag, or any of a dozen similar things. In this case, if you type any of those in, you will be redirected to the proper place. If instead of being redirected you're taken to a search menu, that means that nobody thought of that way of writing it. In that case, just try another form, or try something related like Flag or USA. Once you have found what you were looking for, consider adding redirect pages for the expressions you tried that didn't turn up anything. Chances are you're not the only one thinking about it this way so you'll make life easier for those after you. NamespacesThe default search only applies to the Mainspace, where articles are stored. Other types of content pages can be searched: multimedia, help and project pages, or everything. Searching in a single namespace can be achieved by typing the namespace, a colon, then the search term in the search box, for example Wikipedia:Verifiability returns search results for verifiability in the Wikipedia namespace. To search in any subset of namespaces, click "advanced" on the search form. Depending on the web browser in use, a box may still be checked from a previous search, but without being effective any longer! To make sure, uncheck and then recheck it. Searching the file namespace (multimedia, including images and songs) means searching the file names and descriptions, i.e. the first parts of the file description pages (details). Logged-in users can modify the default namespace to search in preferences. The source text is searchedThe source text (what one sees in the edit box, also called wiki text) is searched. This distinction is relevant for piped links, for interlanguage links (to find links to Chinese articles, search for zh, not for Zhongwen), special characters (if ê is coded as ê it is found searching for ecirc), etc. Delay in updating the search indexFor reasons of efficiency and priority, recent changes are not always immediately taken into account in searches. The index is typically updated every morning GMT. If you see the index lagging more than couple of days, report it at WP:VPT. Display of search resultsLogged in users can choose how much context and how many hits per page to display with a parameter in "My Preferences". Other ways to find pagesFor an overview of how to find and navigate Wikipedia content, see Portal:Contents. Multi-lingual Wikipedia search
Searching for external linksSpecial:Linksearch is a tool for searching for links from Wikipedia articles to sites outside Wikipedia. For example, all Wikipedia pages linking to Yahoo.com. External search enginesIf you cannot find an appropriate page on WikipediaIf there is no appropriate page on Wikipedia, consider creating a page, since 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 Where to ask questions, which is a list of departments where our volunteers answer questions, any question you can possibly imagine. DefinitionsIf you're looking for a straight definition, try our sister project Wiktionary. For definitions of terms used in Wikipedia, check out the glossary or the tutorial's glossary.
