Ah, OK. Then what you're doing is probably best. You're essentially creating a marker for your docs that should be grouped together, and you don't really need any distances here at all.
Actually, this would also work with faceting. You could facet on your geo_city field (and it could even be just the city name, at index time you determine what the right city for each doc is and put that value in). I think facets would be more efficient than using grouping, there's less bookeeping involved. But if your speed is sufficient, why make the change?
