geographic queries, radius unit ?

hi!
I just got one question about geographic queries. for radius filters, the radius parameter is a distance, right?
what is the unit?

hi,
Is my question stupid or nobody knows?

The documentation describes the radius parameter of spatial filters as “The float radius value”.

Hi Jan Jan,

If I remember, this is the distance between two lat/long coordinates, so approximately 69 miles.
