effective googling

here is a trick in google to find a crack for software easily..
for example if you type it as crack for nero 7, it will show about result in lakhs and sometimes it will not relate to crack websites at all.
to find it easily just type your softare name within double quotes and type 94FBR..
that is "nero 7"94FBR ..
the google will reduce to thousands and it will show correctly website which contains key and crack...
