<!-- PLEASE ADD CATEGORIES AND INTERWIKIS AT THE BOTTOM OF THIS PAGE. -->
==Usage==

Creates a Google custom search link, which searches one site (and, optionally, pages with URLs containing one directory path in the site). (If you want to search on the entire Web, use {{Tl|Google}} instead.) This template takes three unnamed input parameters; you must supply the first one, and the last two are optional.

# A domain name, and optionally the first part of directory path (to specify one part of the site to search). (Required.) This parameter becomes the values of the <code>sitesearch=</code> and <code>domains=</code> parameters in the resulting search URL. If the value ends in a directory path component, it evidently must end with a complete path component. For Wikipedia URLs, this would be everything up to a slash, a colon (including or not including the slash or colon has no effect on the resulting search). Delimiting a search with other punctuation characters can sometimes work, such as a trailing opening parenthesis character. Examples:
#* <code>en.wikipedia.org</code> &mdash; (search all of the English Wikipedia)
#* <code>en.wikipedia.org/wiki/Wikipedia:Help_desk</code> &mdash; (search the English Wikipedia Help desk)
#* <code>en.wikipedia.org/wiki/Help:</code> &mdash; (search the English Wikipedia's Help: [[w:Help:Namespace|namespace]])
#* <code>en.wikipedia.org/wiki/Help_</code> &mdash; (generates a search link that does not work: {{Google custom|en.wikipedia.org/wiki/Help_||try it}}, evidently because no Wikipedia page URLs contain the string with a colon or a slash immediately after it)
#* <code>en.wikipedia.org/wiki/Wikipedia:Village_pump_(</code> &mdash; (search the English Wikipedia's Village pump section-specific pages and their archive pages; evidently the trailing open parenthesis character is necessary to make this work)
# Your search term(s). (Optional.) If this parameter is empty, clicking on the resulting link generates a Google search form with an initially blank input field, ready to search on the site the first parameter specifies.
# Link text to display on your wiki page. (Optional.)

=== Do not use in articles ===
{{Warning|Do not use this template in [[WP:WIAA|articles]] (as Google search links [[WP:EL#Links normally to be avoided|are not appropriate in articles]]). The template is only for [[Help:Talk page|talk pages]] and other process pages ([[WP:HD|Help desk]], [[WP:PROJ|WikiProjects]], [[Help:User page|user pages]], etc.). The template will produce an ugly messagebox warning if you attempt to use it in an article.}}

==Examples==

The template allows for some very flexible searching on entire [[Web site]]s, Wikipedia [[Help:Namespace|namespaces]], and [[Help:Subpage|subpage trees]] within Wikipedia.

=== How to search subpage trees within Wikipedia ===

Wikipedia has many [[Help:Talk page|talk pages]] (a.k.a. discussion pages) and other project pages that behave similarly (such as the [[WP:HD|Help desk]], the [[WP:VPT|Village pump]], the [[WP:RD|Reference desk]], as well as announcement pages such as the [[WP:SIGNPOST|Signpost]]). High-volume talk pages typically have [[WP:EIW#Archive|archives]] consisting of subpages. The template can search on any set of archive pages that follows the right naming structure (many if not most archives on Wikipedia do).

[[Wikipedia:Wikipedia Signpost/2008-11-10/Search engine|As of October, 2008]], Wikipedia's internal search became able to search on subpage trees. {{Tl|Search subpages link}} uses this new Wikipedia search feature, and works in some cases where Google search does not.

=== Problem with the Talk: namespace ===

Google searches (both {{Tl|Google}} and {{Tl|Google custom}}) appear to work on the "talk" [[Help:Namespace|namespaces]] associated with some non-[[WP:WIAA|article]] namespaces (such as Wikipedia talk:), but they do not work on the Talk: namespace associated with [[WP:WIAA|article]]s, nor on the User talk: namespace. For example, even a simple Google search for the [[Talk:Psychokinesis]] page: {{Google|Talk:Psychokinesis}} does not return the [[Talk:Psychokinesis]] page on Wikipedia as one of its results. Google does appear to find a copy of that page on somebody's [[WP:MIRROR|mirror wiki]], but not Wikipedia's talk page. The following Google custom searches do not work, either:

{| class="wikitable"
<!-- ! width=280px | Type this !! width=130px | To get this !! What it produces, or searches for -->
! Type this !! To get this !! What it produces, or searches for
|-
| <tt><nowiki>{{google custom|en.wikipedia.org/wiki/Talk:Psychokinesis||Search Talk:Psychokinesis}}</nowiki></tt> || {{google custom|en.wikipedia.org/wiki/Talk:Psychokinesis||Search Talk:Psychokinesis}} || Blank form to search Talk:Psychokinesis and its subpages - does not work
|-
| <tt><nowiki>{{google custom|en.wikipedia.org/wiki/Talk:Psychokinesis/||Search Talk:Psychokinesis}}</nowiki></tt> || {{google custom|en.wikipedia.org/wiki/Talk:Psychokinesis/||Search Talk:Psychokinesis}} || Blank form to search Talk:Psychokinesis and its subpages - does not work, with or without the trailing slash
|-
| <tt><nowiki>{{google custom|en.wikipedia.org/wiki/Talk:||Search the Talk: namespace}}</nowiki></tt> || {{google custom|en.wikipedia.org/wiki/Talk:||Search the Talk: namespace}} || Blank form to search Talk: namespace - does not work
|-

Googling for clues: {{Google|google does not index wikipedia talk pages}} found this blog post by [[User:Cumbrowski]]:
* [http://www.searchenginejournal.com/all-wikipedia-links-are-now-nofollow/4288/ All Wikipedia Links Are Now NOFOLLOW], January 21st, 2007 by CarstenCumbrowski 
which includes a comment posting that says "Google excluded the talk pages from the index". This probably means article talk pages, since Google is still indexing talk pages for non-article pages. {{Tl|Google custom}} therefore will not work on the Talk: namespace.

Wikipedia's internal search can search all of Wikipedia's talk pages. Use {{Tl|Search link}} to generate a link to search an entire talk namespace, and {{Tl|Search subpages link}} to search a subpage tree within a talk namespace on Wikipedia.

=== Other Wikipedia exclusions ===

See Wikipedia's [[robots.txt]] file at http://en.wikipedia.org/robots.txt for a list of content that Wikipedia tells [[search engines]] such as [[Google]] not to index. {{Tl|Google custom}} therefore will not find any content that robots.txt excludes.

=== Problem with moved pages ===

If a page was originally at a name that is now a [[Help:Redirect|redirect]] as a result of a [[Help:Moving a page|move]], evidently Google continues to index the content at the original page name. For example, the page which is now [[Wikipedia:FAQ/Business]] began as [[Wikipedia:Business' FAQ]] (which is now a redirect to the new page). However, Google continues to index the new page content under the old page name, apparently regarding the new page as a more-recent duplicate.

This is not a problem when you search on all of the English Wikipedia, or on the entire Wikipedia: [[Help:Namespace|namespace]], but if you try to search on the [[Wikipedia:FAQ]] subpage tree, Google does not find content on subpages that it indexes through redirects that are outside of the tree.

It may be possible to fix this problem by changing redirects such as [[Wikipedia:Business' FAQ]] to [[Wikipedia:Soft redirect|soft redirects]]. Then the redirect page should not appear to Google to be a duplicate of the content page, at the next time when Google re-indexes Wikipedia. This would slightly inconvenience users who are following links to the redirects, but they would only have to click once more. (As of September 25, 2008 we have not tested this. For research notes, see [[User:Teratornis/Notes#Wikipedia:FAQ search broke]].)

=== Repetitive searches ===

If you need to create a large number of search links on a particular subset of Wikipedia pages, you can save much typing by making a new template. See {{Tl|Google help desk}} and {{Tl|Google wikipedia}} for examples showing how to cut down {{Tl|Google custom}} to make it do one specific kind of custom search. This has been useful for answering questions on the [[WP:HD|Help desk]]. It may be useful on other high-volume [[Help:Talk page|talk pages]], or on process pages that work like talk pages, where users new to a discussion ask the same questions repeatedly.
