Geohash_precision Units?


(Michael Sander) #1

What are the units of geohash_precision when no unit is explicitly
specified?

The docs currently statehttp://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-geo-point-type.html
:

If you enable the geohash option, a geohash “sub-field” will be indexed as,
eg pin.geohash. The length of the geohash is controlled by the
geohash_precision parameter, which can either be set to an absolute length
(eg 12,
the default) or to a distance (eg 1km).

When you set geohash_precision to "an absolute length", what units are you
setting it to? Meters? This seems like such a simple question that I bet
I'm missing something.

Thanks,
