Turn off autocomplete?

Is there any way to turn off the autocomplete 'feature' in iTunes? I'm most concerned about what happens in the iTunes store - for example when searching for 'live' earlier, it overrode my decision and searched for 'the libertines' instead. If I have to disable autocomplete in the whole program to turn it off in the store, that's fine - it is pretty irritating in the main program when editing album names etc.
