Search facilities in MediaWikiThe description below applies when lucene search has been installed, like on the Wikimedia sites. On every page there is a search button with search box. See also "Search result settings" section in the preferences. TipsAvoid short and common wordsThis is the most likely cause of an unexpected failed search. If your search terms include a common "stop word" (such as "the", "one", "your", "more", "right", "while", "when", "who", "which", "such", "every", "about", "onto"), then your search will fail without any results. Short numbers, and words that appear in half of all pages, will also not be found. In this case, drop those words and rerun the search.
See Help:Short words in searches for a procedure to allow MySQL to index words shorter than four letters. Search is case-insensitiveThe searches for "fortran", "Fortran" and "FORTRAN" all return the same results. Words with special charactersIn a search for a word with a diaeresis, such as Sint Odiliënberg, it depends whether this ë is stored as one character or as "ë". In the first case one can simply search for Odilienberg (or Odiliënberg); 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 Help:Special characters. PhraseSearch for a phrase by enclosing it in double quotation marks. WildcardYou can use a wildcard *, at the end of a search term only. To search for pages with the words "boat" or "boats" search like this: "boat*". You cannot use "*boat" to find Riverboat, etc. Searching limitations and GotchasNo regular expressionsYou cannot use regular expressions. Words in single quotesIf a word appears in a page 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 pages, for which this problem does not arise. 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. Delay in updating the search indexFor reasons of efficiency and priority, very recent changes to pages are not always immediately taken into account in searches. Search optionsNamespaces searchedThe search only applies to the namespaces selected in the 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 may no longer be effective. To be sure the box is in effect, uncheck and recheck it. Searching the image namespace means searching the image descriptions, i.e. the first parts of the image pages. For searching the titles, use Special:Imagelist. Searching in single namespaces can also be achieved by typing the namespace, a colon, then the search term in the search box. For example, typing "Talk:Foo" will give all pages containing "foo" in the talk namespace. The URL for searching a particular namespace is where "qqq" is used as example for the search term, and the namespaces to be searched are specified. Thus, e.g. http://en.wikipedia.org/description/Special:Search?ns10=1&ns11=1&fulltext=Search&search=test searches the Template and Template talk namespaces for "test", and http://en.wikipedia.org/description/Special:Search?ns6=1&fulltext=Search&search=jpg searches the image description pages for "jpg". To search the Help pages use http://en.wikipedia.org/description/Special:Search?ns12=1&fulltext=Search&search=x and replace the x in the URL by the search term. Replacing it in the search box does not work the same: the search is then in the namespaces specified in the preferences, instead of just in the help namespace. For each namespace: all 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 (Also there is a special search feature Special:Imagelist, which searches in titles, regardless of whether there is an image description.) Languages searchedSee the feature request at MediaZilla:1837. Redirects can be excludedCheck or uncheck the tickbox "List redirects" in "Search in namespaces" box found at the bottom of a search results page. The wikitext is searchedThe wikitext (source text, what one sees in the edit box) is searched. This distinction is relevant for piped links, for interlanguage links, special characters (if ê is coded as ê it is found searching for ecirc), etc. HighlightingSome portions of matching pages that contain the searched-for terms are shown, with the terms highlighted in red. You can set the number of lines extracted and the amount of text per line shown in your preferences. If you search e.g. for "book" you get only pages with that word, not pages with "books" only. However, on pages with "book" and "books", also the part "book" of the word "books" is highlighted. Other possibilitieslist of all pages
Please note that a-z come after A-Z. For some other namespaces, see Help:Namespace. Go buttonSee also Help:Go button. Search fieldPressing the [Enter] key while the search field is active is equivalent to clicking on the [Go] button. While this is obvious when using Internet Explorer (tested on version 6), Mozilla (version 1.6 at least) provides no such indication. Search enginesThe URL searches for the phrase interwiki link in wikipedia.org — that is, in all Wikipedias as well as Wikisource (sources.wikipedia.org) and meta.wikipedia.org, but not meta.wikimedia.org. %3A is a colon (:), %22 a double quotation mark ("), and + is equivalent to a space ( ); %20 may also be used for a space. (See also Help:URL.) Note that the underscore (_) is not equivalent to a space: putting it in the URL results in a search for a word containing actual underscores at those positions. Thus finds pages containing the term interwiki_link. In an interwiki link with prefix "google:", a double quotation mark (") is again written %22, but now a space needs to be written " ". ExamplesSearching for the phrase "michael jackson":
Searching for first term only:
Searching for two terms, not the phrase: Searching for phrase with underscore: Thumbnails in Google cacheBrowse Wikipedia images with thumbnails in Google cache: png jpg gif Each thumbnail links to an image result page, which links both to the Wikipedia image page and to the image itself on Wikimedia.

Administration Optionsfrom includes/DefaultSettings.php, apparently you have to look up your namespace table, because they are numbered... $wgNamespacesToBeSearchedDefault = array( -1 => 0, 0 => 1, 1 => 0, 2 => 0, 3 => 0, 4 => 0, 5 => 0, 6 => 0, 7 => 0, 8 => 0, 9 => 1, 10 => 0, 11 => 1 ); I would guess that -1 is the default settings.. and 0 is main namespace.. and 0 is off and 1 is on.

For the resulting pages the following is shown:
This page is a copy of the master help page at Meta (for general help information all Wikimedia projects can use), with two Wikipedia-specific templates inserted. To update the main text, edit the master help page for all projects at m:Help:Searching. For Wikipedia-specific issues, use Template:Ph:Searching (the extra text at the bottom of this page) or Template:Phh:Searching for a Wikipedia-specific lead (text appears at the top of this page). You are welcome to replace the full wikitext of this page with that of the master page at Meta at any time. To view this page in other languages see the master page at Meta.
