True -- I found the geohash on a separate page. I was using it because it can allow for multiple points, and I was hoping to be ahead of the curve for allowing that feature for the data I'm managing.
I can roll back and use the LatLon type -- but then I'm still concerned about the bounding box giving results outside the specified range. Or would I be better off just indexing a lat & lon in separate fields, then making a normal numeric ranged search against them. -- Chris On Thu, Oct 27, 2011 at 3:09 PM, Yonik Seeley <yo...@lucidimagination.com> wrote: > On Thu, Oct 27, 2011 at 2:34 PM, Christopher Gross <cogr...@gmail.com> wrote: >> I'm using the geohash field to store points for my data.
