xgreat britain » great britain, great brittain, great britains
zgreat britain » great britain, great brittain, great britains

• Adding a wildcard symbol may retrieve word variants: %((xgreat britain) or (zgreat britain)) %((p colonies) or (et colonies)) %((2f administration) or (trf administration))%22*.
