ਫਰਮਾ:Search link
This template creates a link that can be used to store a Wikipedia search box query. A search link is useful for collaborative search on Talk pages and most other pages, but it is not to be used in articles. If used in articles, it outputs the above warning. Basics
The name of the template is Search link, or sl for short. Both a search link and a search box go to the same search engine. The same query produces the same result. The basic search covers articles. It finds words and phrases composed of letters and numbers very quickly, but a basic search can also query for all articles that contain a string that includes punctuation, math, and other symbols as seen in the page content or as seen in the page wikitext.
This template differs from the search box superficially when searching for an equals sign. In the search box you just say =, but here you must use the five-letter string {{=}}.[2] In search 5 notice the need for the double quotes around the search pattern: Search 2 exemplifies the easiest filter to apply to accompany any regexp search. It just takes the same phrase and make it a separate term. Given any regexp insource/"exact string search"/, just accompany it by an insource:"exact string search". The later term will always act like a perfect filter, matching every alphanumeric, and ignoring every non-alphanumeric, speeding through an indexed search to filter out pages the regexp couldn't possibly match. As for other filters, a namespace is weak, but every additional term increases regex power. The next section covers Search link arguments more in depth.

Here are the template parameters for Search link.
You only ever need to use parameters 3–20 if you want a profile of two or more namespaces for a search domain. Otherwise you can just say the namespace name (or all) at the beginning of the query, or a prefix parameter at the end of the query. When the query goes through this template, the default search domain is article space, just as it is for basic users. The default search domain of a user, logged-in or not, is article space unless the user set their preference.[3] But no matter who uses a search link the results will always be the same. "Cut and paste" can never guarantee the same results for a search, but a search link can because the search domain is just article space for everyone, or search domain is the set of namespaces you set for everyone. If you know the numbers of your search domain profile, you just type them in If you have just one namespace in your search link, and it's not article space, you can specify it by saying, say, ns=ns10, or |ns10" at parameter position 3 or greater:
For one namespace the explicit name is preferred:
The explicit name is preferred if you will be publishing or saving your search link. That way when it is run later the search domain shows up explicitly at the beginning of the search box of the search results page to inform the user. Otherwise only the URL and only the namespace-profile dialog frame pops up on the search results page to inform the user. When it is two or more namespaces, these things always happen, because the query only accepts one namespace (as the first term only). But all is also an informative query, a pseudo-namespace for Search only. If you see a query begin with all:, the URL will be loaded with all the namespace parameters. You can use "all" in {{Search link}} to specify all namespaces:
but again, it is far more preferable to say
than it is to use:
for the reasons given just above. But when specifying "all", the query time is about seven times greater because there are that many more pages on the wiki than there are articles. If a more targeted search is possible, it runs much more quickly than the "all" search. For example, if you have a query for which know the search domain is 10 and 11, and you want no label, then you need a parameter 3, but you need no parameter 2, so per the template parameter rules the search link can be made in four general ways:
For another example, if you select the "Wikipedia" and "Help" namespaces, then run a query, the URL will show Note how the URL contains ns0, ns1, ns2, and ns3, and how it got them:
If you need to develop a highly specific search domain, a very elaborate one carved out of a set of the thirty namespaces, then you will have developed this at the search results page using the Advanced search domain picker there. Then you just cut and paste the entire string from the URL of your found search domain namespaces, and paste it into one named parameter To type in namespaces 0, 2, 4, 5, 7 and 9, with no label, the two easiest ways are:
The order is irrelevant. Advanced examplesAll these involve
The need to match an equals in an article is not surprising, and is basic. You have to use {{=}} or Regex are sensitive to punctuation, brackets, math and other symbolic characters, collectively known as "punctuation" so you quote them, because otherwise they have their regex metacharacter meaning. The "metacharacters" of CirrusSearch have claimed most punctuation characters as functions in their regex, but you don't have to know all the metacharacter functions just to search for them as targets literally. You can simply quote all punctuation to search for them as literal targets in wikitext. The way to easily quote every character in an entire regexp is to put the whole term in quotes: insource:/"regexp with literal characters"/ To get a pipe character through both the template and the search engine to target it as a character in wikitext, you have to quote it twice, hence the frequent need for the six characters \{{!}} in an advanced search link. The equals sign is not a metacharacter, so it does not have to be quoted twice, as the pipe character does. The pipe character is a metacharacter that means OR. To generate advanced regex searches, see about doing so at {{regex}}. ਮਦਦ:Searching/Featuresਮਦਦ:Searching/Regexਮਦਦ:Searching/Regex/Sandboxing See alsoTemplates for searching WikipediaSearch linksA search link stores a query in a link that takes you to live search results for that stored search. They're found on user pages and talk pages. Use one to bring the full feature set of MediaWiki Search, or features of external search engines, to bear on users unfamiliar with their search parameters. One type of search link is a wikilink with all the capabilities of Search (search box), and with standard wikilink syntax: [[Special:Search/query| label]]. So this search link will (1) navigate: [[Special:search/Wales]] → Special:search/Wales or (2) search: [[Special:search/~Wales | search/~Wales]] → search/~Wales if you prefix a ~ tilde character. All other search links are made from a template that will build a URL instead of wikilink. A URL can for example can call off-site search engines to search Wikipedia.
