Wikipedia has its own search engine, with its ''search box'' on every page. The search box will go to a given ''page name'', but there are three ways to go to the ''search results'' page instead. 1) If you activate the magnifying-glass icon from an empty ''search box'', you'll go to an empty ''search results'' page. 2) If you start any query with the tilde character, it always generates ''search results'', ''page name''. (This is explained below.) 3) Choose "" from the page names that drop-down as you type (if you have JavaScript enabled). To access the ''suggestions'' that drop down as you type, click the mouse on them, or use , or tab, to access them. Two central features of the ''search results'' page are a ''search box'' with larger font for editing the query that landed you there, and below that a collapsible frame for activating a ''search domain''. The "Advanced" ''search domain'' is a selection of every type of page on Wikipedia, in areas called ''namespaces''. If you try to ''navigate'' from the featured ''search box'', you'll only get a preliminary report saying that :There is a page named "", with a link to the page. To navigate to a page instead of search, remember to type the page name into the usual ''search box'' there (on any page). As is normal for web search engines: * Characters that are not numbers or letters (punctuation marks, brackets and slashes, math and other symbols) are ignored. * Stemming is performed to aggressively boost the number of ''search results''. * Spelling corrections and query corrections are offered. * A hyphen means ''not'', and turns a "yes include" query term into a "no" term, for example while -refining -unwanted ''search results''. * When you land on ''Search'', the query that produced it will show in its own featured ''search box'', in large font, for editing. See below for how to turn your browser web-search box into a Wikipedia-search box. Advanced features of the Wikipedia search engine include multi-word proximity-searches, wildcard searches, "fuzzy~" searches, searching with regular expressions, search domains and namespaces. Wikipedia's search engine also has several, wiki-oriented, operators and parameters, for weighting and filtering. (See Syntax below.) For more information on the ''search box'', see ''Search engine features'', below. For searching for other than a page name, such as searching a page history, or for other content, see ''Special searches'' below. ''Special:Preferences'' offers several search options, and ''Wikipedia:Tools#Searching'' offers the setups of other users. ==Search results page== You land on the page ''Search'' by way of * an empty search * ] The first two have empty queries, and the last two do not. You can also land on the ''Search'' page of Wikipedia by using your web browser search box ''from any web page''. See below for how. In the search results * The ordering of the list of search results is determined by the page ranking software, but you can make adjustments to it. See ''#Search engine features'' below. * Matching terms are highlighted in bold. All matches in the title ''will'' show, and all other matches ''can'' show in the ''snippet'', but all matches ''will not'' show when they are far apart on the page. Search terms are not thrown out, but some page item may contain only a ''stem''. * Sometimes the match is made in a section heading. These will show off to the side of the page name, parenthetically. * For articles, a message box may show up beside a listing, indicating that it has a sister page on another project, such as a Wiktionary entry that defines the title of a Wikipedia article. Search results will often be accompanied by a preliminary report. *There is a page named "" (a wikilink to an existing page), * ' (either a wikilink or a search-link). *''You may create the page ""'' (a redlink to a new page name). The ''Did you mean'' report corrects dictionary word spellings and gives a link that is either a wikilink that will navigation to an article or a search link that will perform a query. The distinction can be made by observing the presence of a ''You may create the page'' report. Another report corrects "spellings" to coincide with any "word" found in a search index (any word on the wiki). : . (two search links). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Help:Searching」の詳細全文を読む スポンサード リンク
