The patch is in r19034 that did not make it in REL1_9 branch. I 
backported with r19460. Hopefully it will be available in 1.9.1 unless 
there is a serious flaw I am not aware of and the release manager find it :)


The problem was that the ajax search function parse the search term 
enclosed in [[]]. This way if someone is looking for 'foobar' and there 
is a 'foobar' article, it can click it directly. The problem is that the 
parser actually need a title to work with which was never created.


The command to grab the patch for a 1.9.0 installation is (all on one 
line) :

svn diff http://svn.wikimedia.org/svnroot/mediawiki@19033 
http://svn.wikimedia.org/svnroot/mediawiki@19034

cheers,
