Editing Help:Searching (section)

== Other search tools ==

Other search tools include:
* Your own browser, to search the current page only. Try {{keypress|Ctrl|F}}, {{keypress|F3}}, or {{keypress|Command|F}}.
* https://www.wikipedia.org<nowiki />, to search other language editions of Wikipedia.
* Search-related templates {{nomirror|{{crossref|pw=y|See the [[WP:Nav box|navigation box]] below.)}} }}

Internal search tools:
* [[Special:BookSources|ISBN]]
* [[Special:PrefixIndex|Prefix]]
* And many other [[Special:SpecialPages|SpecialPages]]

{{anchor|grep}}
External tools dedicated to Wikipedia Database searches include:
* '''[https://grep.toolforge.org/index.php?lang=en&wiki=wikipedia&ns=0 Article title grep]''': searches page titles using [[regular expression]]s. This search is much slower than standard search. In particular this tool can search for exact [[String (computer science)|strings of characters]], including punctuation and with [[case sensitivity]]. For example the pattern {{kbd|\(&&nbsp;Co\.&nbsp;Ltd\.}} will find only titles containing {{kbd|(&&nbsp;Co.&nbsp;Ltd.}} exactly as shown. Regular expressions are precisely defined, and not intuitively obvious.
* '''[https://petscan.wmflabs.org/ PetScan]''': about 20 search parameters, three for categories
* '''[http://wikipedia.ramselehof.de/wikiblame.php WikiBlame]''': search for text in the revision history of a page
* '''[https://sigma.toolforge.org/usersearch.py User Contribution Search]''': reports anyone's contributions to a page
* '''[[:toolforge:sigma/summary.py|Edit summary search]]''': search for text in anyone's edit summaries
* '''[https://whichsub.toolforge.org/ whichsub]''': finds transcluded templates of a given page which contain a given string.
