===Refinement using inclusion control===

{{Further|Help:Template#Noinclude, includeonly, and onlyinclude}}

Sometimes, a passage will almost fit for a transclusion, but not quite. In these cases, you can edit the source page to add <code><nowiki><noinclude>...</noinclude></nowiki></code> tags around content you don't want in the excerpt and <code><nowiki><includeonly>...</includeonly></nowiki></code> tags around content you want only in the excerpt.

For instance, the page [[COVID-19 misinformation]] begins with "The [[COVID-19 pandemic]] has resulted in [[misinformation]]...". However, when excerpting this lead to the misinformation section of [[COVID-19 pandemic]], we don't need to specify which pandemic we're referring to. Therefore, the code <code><nowiki>The <noinclude>[[COVID-19 pandemic]]</noinclude><includeonly>pandemic</includeonly> has resulted in [[misinformation]]</nowiki></code> can be used at the misinformation page, so that it will appear at the pandemic page as "The pandemic has resulted in [[misinformation]]...".

For pages with a high volume of edits, it may be a good idea to leave a hidden comment explaining why the tags are there, so that no one will be [[WP:FENCE|tempted]] to remove them, like so: <code><nowiki>The <noinclude>[[COVID-19 pandemic]]</noinclude><!--These tags are used to refine the excerpt at [[COVID-19 pandemic]]--><includeonly>pandemic</includeonly> has resulted in [[misinformation]]</nowiki></code>

Please note that when the <code><nowiki></noinclude></nowiki></code> tag is wrapped into a new line, a character next to it would be interpreted as a line beginning. This can lead to some formatting problems. For example, when a <code><nowiki></noinclude></nowiki></code> at line beginning is succeeded by a [[whitespace character]], the page engine would translate this as a [[Help:Wikitext#Limiting formatting / escaping wiki markup|leading space]] that renders the subsequent paragraph in [[code block]] and [[monospaced font]] with preserved formatting. For this reason, no spaces should separate the <code><nowiki></noinclude></nowiki></code> tag from the text it precedes.
