• Added labels: Priority-High
• Removed labels: Priority-Medium

Search URLs can take one of two formats. For example:

http://en.wikipedia.org/wiki/Special:Search?search=left+search+box&go=Go
http://en.wikipedia.org/w/index.php?title=Special%3ASearch&search=research+main&
ns0=1&fulltext=Search

A more inclusive expression seems to result in successful matches for either of 
the
examples above:

^http[s]?://[^.]{2,3}\.wikipedia\.org/(.*)search=([^&]+)
