docValues is a safer default. UIF needs to rebuild every time the index is changed (and is also one reason why it's faster once it is built). If one uses real docValues (at index time), then there will even be less heap memory. A note to those trying out UIF: method=uif is an execution hint only and will be ignored if you've indexed docValues. We should probably add some way of forcing it at some point. -Yonik
