Thanks, Roan.
I tried that, and it still gives me the mediawiki search results for Einstein - for instance, I dont see the first image on the Einstein wikipedia page which is File:Einstein1921_by_F_Schmutzer_4.jpg - I get a different set of results - the first being File:Albert_Einstein_Head.jpg - now this works fine for Einstein, but in the case of University of Zurich page, I get an insect as the first result, whereas I would like to get the university of Zurich logo, which is the first image in the infobox on the page.
Thanks
