The one place where there is a real difference is with String faceting as >= 2 segments means that String ordinals must be coordinated between segments. Depending on faceting method this is done up-front (with an obvious fist-call time penalty, some memory overhead to hold the mapping and a slight running overhead for consulting the map) or on- the-fly (with non-surprising running overhead). It becomes relevant with large indexes and/or setups where performance is very important. - Toke Eskildsen, Royal Danish library
