| {{kbd|insource:{{var|word}}}}<br />{{kbd|insource:"{{var|word1&nbsp;word2}}"}}
| Like word searches and exact-phrase searches, non-alphanumeric characters are ignored, and proximity and fuzziness are options.
|-
| {{kbd|insource:/{{var|regexp}}/}}<br />{{kbd|insource:/{{var|regexp}}/i}}
| These are [[Help:Searching/Regex|regular expressions]]. They use a lot of processing power, so we can only allow a few at a time on the search cluster, but they are very powerful. The version with the extra <code>i</code> runs the expression case-insensitive, and is even less efficient. Regex searches are likely to time out unless you further limit the search in some way, such as by including another parameter or a search term outside of the insource component of the search string. (For example, {{kbd|X* intitle:/X/}} to restrict the search to initial position.) {{crossref|pw=y|For more details, see [[mw:Help:CirrusSearch#Regular expression searches]].}}
