Issue solved. Thank you CKoerner (WMF).
In the English version, the base of all translations (!), the first sentence is broken in the moment. It seems like a corruption of Help:Searching:
What was the intended information?
It looks like that content was moved up from another section, where it was already incorrect english. Unfortunately the diff interface in wikimedia (and really most things that track text changes) is unsufficient for finding where the source of this content was or what edit's changed this particular piece of content. If i had to guess it should read something like:
CirrusSearch is the quickest way to find information in MediaWiki. On every page there is a search box.
Thanks for your answer. Are you able to fix this, or do you know, how to inform a translation admin about his issue?
@Speravir, I cleaned it up a little. Special:CirrusSearch is linked from all Wikimedia projects Special:Search pages (unless the local community has modified the link to point to a different, often local, page).
Here's the Special:Search page on the Macedonian Wikipedia. Look for the "? Помош" link in the right corner to see how this help page is being referenced.
I appreciate @Iniquity's help in trying to make the introduction more welcoming. I modified the language to reference search in a generic way, not just here on MediaWiki.org. I hope that my edits didn't break things too much. :) Additional contributions are welcome!
One final note, Help:CirrusSearch describes how the search works on Wikimedia projects, all of which are using the CirrusSearch MediaWiki extension. However, Help:Searching describes the search feature in the default MediaWiki software. There is some overlap in how these two searches work, but do take care in coping information between the help pages. Some information does not apply to both! :)
