Whatever you type into the search boxis called the "search string". It may also be referred to as the "search query". A basic search string is simply the topic you are interested in reading about. A direct match of a basic search string will navigate you directly to Wikipedia's article that has that title. A non-match, or any other type of search string will take you to Wikipedia's search results page, where the results of your search are displayed. Terms in the search string are subject to stem matching, except for anything included between double quotation marks. You can include in your search string special characters and parametersthat activate specific search capabilities. Using any of these will take you to Wikipedia's search results page with the results of your search displayed. The maximum search string is 300 characters long. The format of the text that is entered is called search string syntax.
Search is case insensitive, that is, upper and lowercase is ignored. Search "folds" character families, matching similar-looking letters across alphabets, to match foreign terms. So, you don't have to type in diacritical letters, and your terms will still match. For example, Citroen will match Citroën, and Aeroskobing matches Ærøskøbing. Characters that are not numbers or letters (punctuation marks, brackets and slashes, math and other symbols) are generally ignored. For example, Credit (finance) will return articles with the words credit and finance, ignoring the parentheses, unless an article with exact title Credit (finance) exists. Similarly, a search for the string |LT| (letters LT between two pipe symbols) will only return articles with lt. In order to search for terms that contain non-alphanumeric characters, a regex search must be used instead (using the \\ escape character if required), for example insource:/\\|LT\\|/ will successfully return all instances of |LT|. The source...
The search page features a search box, with some links to search domains beneath it. For information on what can by typed into the search box, see Search string syntaxabove. The main difference between this search box and the one that appears on article pages is that exact matches on this one will not navigate you directly to an article page. This search box will produce the search results pageshowing what all matches your search on Wikipedia. To get to the search page, do an empty search (press ↵ Enter while in the search box before typing anything else in), or click on the magnifying glass in the search box. The link Special:Search, which can be inserted onto user pages or project pages, for example, also leads to the search page. For an explanation of the controls available on the search page, see Refining resultsbelow. While the entire contents of the search page is included in the search results page, it is a distinct page. User scripts might be designed to work on the search r...
The search results page looks just like the search page, with the results for your search query presented below it. For information on what can by typed into the search box, see Search string syntaxabove. The search results page is displayed when a search is done from the search page, when a search from the regular search box does not exactly match a page title, or when any parameters or special characters are included in a search string.
Searching within a page
The internal search engine cannot locate occurrences of a string within the page you are viewing but browsers can usually do this with Ctrl+F, or ⌘ Command+Fon a Mac.
Searching for a specific person's contributions
Due to the way the wikimedia database is indexed, there's no direct way to search for something like insource:foo author:person. But, you can come close in some situations. If you're looking for something on a talk (or, sometimes, project) page, people tend to leave a signature after each edit, and such pages are usually set up so old edits roll off onto archive pages. In this case, the proximity search operator can find instances of your search term near the user's name. Something like foo p...
Search Wikipedia from any web page
To get Wikipedia search results while on any web page, you can temporarily set your web browser's search box to become a Wikipedia search search box, even though you're on another web site; see Help:Searching from a web browser. This trick removes the need to first navigate to Wikipedia from a web page, and thendo the search or navigation. It is a temporary change, and then you put it back to your preferred web-search engine. You can just drag items on the page the name up to the web browser...
Other search tools include 1. your own browser, to search the current page only. Try Ctrl+F, F3, or ⌘ Command+F. 2. the Main page. It searches other-language Wikipedias. 3. search-related templates. See the navigation boxbelow. Internal search tools: 1. ISBN 2. Prefix 3. and many other SpecialPages External tools dedicated to Wikipedia Database searches include: 1. Article title grep: searches page titles using regular expressions. This search is much slower than standard search. In particular this tool can search for exact strings of characters, including punctuation and with case sensitivity. For example the pattern \\(& Co\\. Ltd\\. will find only titles containing (& Co. Ltd.exactly as shown. Regular expressions are precisely defined, and not intuitively obvious. 2. PetScan: about 20 search parameters, three for categories 3. WikiBlame: search for text in the revision history of a page 4. User Contribution Search: reports anyone's contributions to a page 5. whichsub: finds transclu...
If you're looking for a place where wine comes from pronounced "Bordo", you can try searching for a more general article such as "Wine", "Wine regions" (returning "List of wine-producing regions") or other wine types such as "Burgundy" and see if it's mentioned there or follow links (in this case, to "Burgundy wine", which has several mentions of "Bordeaux", and links to "French wine" and "Bordeaux wine"). If you know it's in France, look at "France" or the Category:Cities in France, from where you can easily find Bordeaux. You can try various things depending upon the particular case; for "Bordo" wine, it's quite likely that the first letters are "bord", so search an article you've landed on for these letters. If you use Google to search Wikipedia, and click on "cache" at the bottom of any result in the search engine results page, you'll see the word(s) that you searched for highlighted in context. For an overview of how to find and navigate Wikipedia content, see Wikipedia:Content...
To power its search feature, Wikipedia uses CirrusSearch, a MediaWiki extension that uses Elasticsearchto provide enhanced search features.
Wikipedia Search works great about two-thirds (2/3) of the time. About every third day the extension stops working. I will type wiki, press the spacebar, enter my query, and press return.
