wiki filter prefixes

You can easily link to terms in wikis and various other websites using a simplified markup syntax. For example, "[prefix:some term]" creates a hyperlink to the "some term" article on the website specified by "prefix." It is also possible to use the "|" character to create a "piped link," with display text that is different from the search term. For example, "[w:public transport|public transportation]" would be translated as a reference to the Wikipedia article on "public transport" that displays as "public transportation."
