Among LatLonType & SpatialRecursivePrefixTreeFieldType which one for filtering outside of bounding box?

[user 01 <us...@gmail.com>]

For geospatial search, I need to filter out all points outside of certain
radius from a certain point. No need for precise results, Approximation
will work for me! No sorting is required either. I see there are two
Spatial impls: LatLonType & SpatialRecursivePrefixTreeFieldType. But I am
sure which one should I choose for good performance & less memory?
(As I said approximations are ok for me. Instead of circle if it gives me
approx bounding box results then too I will be fine)

Use the location_rpt field type in the example schema.xml -- it has "good
performance & less memory" (what you asked for) compared to LatLonType.
To learn how to tweak some of the settings to get better performance at
the expense of some accuracy, see
