This feature is part of an InterWiki
strategy. It allows you to not only search the local site but also some of the sites on the NearMap
This is an implementation of MetaWiki and InterWikiSearch (see MetaWikiDiscussion), built directly into the wiki engine itself. This makes it very easy for other wikis to deploy it.
For a test, follow this link:
Note that my homepage is near-linked to Meatball, so the page "ChrisPurcell" is also found. When you follow the link "Search sites on the NearMap as well", you will find the term on Community Wiki and Emacs Wiki. -- AlexSchroeder
I have search proxies for UseMod and MoinMoin wikis... See Oddmuse:Near_Links. -- AlexSchroeder
