==Google search trick to help with suffixes==
In Google search, try the following (quote marks included): 
* <nowiki>"http://en.wikipedia.org/wiki/*%s"</nowiki>
* <nowiki>"http://en.wikipedia.org/wiki/ * %s"</nowiki> 
where you replace "%s" with the suffix you're interested in. It's imperfect but useful. [[User:Three-quarter-ten|—&nbsp;¾-10]] 20:11, 13 February 2010 (UTC)

This will find references to those pages on other sites as well, you'd be better off with:
* <nowiki>site:en.wikipedia.org inurl:"wiki/*%s"</nowiki>
* <nowiki>site:en.wikipedia.org inurl:%s</nowiki> (assuming your string isn't present in "en.wikipedia.org/wiki")

== Passing parameters in wikilink ==

Is it possible to pass parameters in a wikilink to the PrefixIndex page as can be done in the transclusion syntax?

I.e like:

<code><nowiki>((Special:PrefixIndex/((FULLPAGENAME))/ |hideredirects=1 |stripprefix=1))</nowiki></code>
If so, what's the proper syntax?

== Search with trailing space ==

I wish to search all articles (and exclude redirects) that start with ''Dr'' without the dot after it. I understand that I cannot enclose the search term with quotes. If it was allowed, I only had to enter "Dr " with a space. But giving Dr followed by a space, is not working as the search seems to be removing the trailing space. Giving Dr. with a space after it also is returning results (such as [[Dr.I]]) that do not have space after Dr. .

:@[[User:Jay|Jay]], You might want to try a [[regex]] search e.g. <code>intitle:/Dr((nbsp))/</code>&nbsp;&#8213;&nbsp;[[User:Qwerfjkl|<span style="background:#1d9ffc; color:white; padding:5px; box-shadow:darkgray 2px 2px 2px;">Qwerfjkl</span>]][[User talk:Qwerfjkl|<span style="background:#79c0f2;color:white; padding:2px; box-shadow:darkgray 2px 2px 2px;">talk</span>]] 08:01, 22 December 2021 (UTC)

== Substing this page? ==

Is there any way to subst the special page? [[User:EpicPupper|🐶 EpicPupper]] <sup>(he/him &#124; [[User talk:EpicPupper|talk]])</sup> 19:24, 23 February 2022 (UTC)
:((Yo|EpicPupper)) Not the obvious way [[Special:Diff/1075867907|1]], [[Special:Diff/1075867928‎|2]]. And the [[mw:Special:PrefixIndex]] links back to this enwiki page for documentation, I don't see any docs on the mediawiki site, nor does there exist an [[mw:Project:Special:PrefixIndex]], like there is a [[en:Project:Special:PrefixIndex]]. I did figure you tried all that but I'm replying again just to see if anyone else with this on their watchlist has an ideas.

== Hiding disambiguations ==

Is there any way to hide disambiguation pages when searching for articles beginning with certain characters? I know redirects can be hidden but can disambiguations be hidden? If not, would it be feasible to add such a feature? [[User:Denniscabrams|Dennis C. Abrams]] ([[User talk:Denniscabrams|talk]]) 14:05, 2 January 2024 (UTC)
:Not directly through this special page, but fortunately there is through [[Special:Search]]:
:[[Special:Search/-"(disambiguation)" prefix:Foo]] gives page titles beginning with "Foo" that ''do not'' contain "(disambiguation)". (Technically this doesn't filter out [[WP:NOPRIMARYTOPIC]] disambigs, which don't have "(disambiguation)" in the title, but hopefully that will be enough.)
:For more see [[Help:Searching]]. However, this, in turn, doesn't let you control redirects showing up in the results, because the MediaWiki software doesn't support that: [[phab:T204089]]. If you really need to filter out '''both''' disambigs and redirs in an automated fashion, you'll have to code up something to fetch the search results and do that filtering locally, or ask someone for assistance with same.
:If curious as to why: redirs are something handled specially inside the MediaWiki software, so it "knows" automatically whether or not a page is a redirect. Disambigs on the other hand, are just a page-titling convention Wikipedia's humans use to organize pages; the software doesn't "know" whether a page is a disambig.
:Hope this helps, and if you have more questions ask away! ((=))) [[User:Slowking Man|Slowking Man]] ([[User talk:Slowking Man|talk]]) 18:48, 2 January 2024 (UTC)
::[[User:Slowking Man|Slowking Man]], I'm not sure that's quite right. Links to disambiguation pages have a special class, and I believe disambiguation pages are marked with a magic word, something like <code><nowiki>__DISAMBIG__</nowiki></code>.<span id="Qwerfjkl:1704222450182:Wikipedia_talkFTTCLNSpecialFTTCLNPrefixIndex" class="FTTCmt"> —&nbsp;[[User:Qwerfjkl|<span style="background:#1d9ffc; color:white; padding:5px; box-shadow:darkgray 2px 2px 2px;">Qwerfjkl</span>]][[User talk:Qwerfjkl|<span style="background:#79c0f2;color:white; padding:2px; box-shadow:darkgray 2px 2px 2px;">talk</span>]] 19:07, 2 January 2024 (UTC)</span>
:::Ah-ha! Turns out here on Wikipedia we have an extension that does that: [[mw:Extension:Disambiguator]]. Thanks for bringing that up. However it looks like unfortunately not "hooked in" to Special:Search at present, so filtering disambigs from there is still not possible. You have to go through the [[Help:API|API]] and do some complex querying. [[User:Slowking Man|Slowking Man]] ([[User talk:Slowking Man|talk]]) 23:28, 2 January 2024 (UTC)
