Hmmm, seems like we could really do with a geofilt() function that's
just like geodist() but with the first parameter being distance so we
could avoid calculating the distance for every doc. And of course the
new exists() method (it's just internal now, but should be exposed via
a function) would be false if the doc was outside of the distance.
The best we could do out of the box right now is try to utilize the
geofilt query and default it to a high number where it doesn't match:
facet.query={!frange l=5.001 u=3000}query($gf,10000)&gf={!geofilt d=3000}
Of course if the lower bound is 0, you can use it directly!
facet.query={!geofilt d=3000}
