If you didn't have a surname or the like do you get results and if so what format do they come in?
I think that @historicus has probably given the DS answer to that one.
Even with full service details (No, Rank and Name), I always start with the premise that 'less is more'. That way, if you turn rafts of similarly named people, you can use the information you have to narrow things down.
It also (usually) allows you to pick up any changes of Regt or Corps as such transfers meant the issue of a new Service number.
Much like Historicus, I also had a play around with trying to identify the KIA, only I used the time period 1 July to 30 November 1916: 'George', Cheshire Regt' and 'KIA' produced far too many hits. If that time period was extended to end December 1916, it increases exponentially.
. . . and, just to be really 'glass half empty', it's quite possible that 'George' was not his given first name but simply family usage of a second name, a trait that has led me on some really frustrating searches in the past.
