Grant Ingersoll commented on SOLR-1586:
---------------------------------------
There is an example of what goes in the schema on this patch:
{code}
<!--
A CartesianTier is like a set of zoom levels on an interactive map (i.e.
Google Maps or MapQuest). It takes a lat/lon
field and indexes it into (endTier - startTier) different fields, each
representing a different zoom level.
This can then be leveraged to quickly narrow the search space by creating
a filter, at an appropriate tier level,
that only has to enumerate a minimum number of terms.
See http://wiki.apache.org/solr/SpatialSearch
-->
<fieldType name="tier" class="solr.CartesianTierField" start="4" end="15"
subFieldSuffix="_d"/>
{code}
I think the filter question is best answered on SOLR-1568, but I'll give a
brief thought. Something like:
{code}
&fq={!tier dist=20}location:49.32,-79.0
{code}
or it could be:
{code}
&fq={!tier lat=49.32 lat=-79.0 dist=20}
{code}
I'm not sure which I prefer.

> Per SOLR-773, create field types that hid the details of creating tiers,
> geohash and lat/lon fields.
> Fields should take in lat/lon points in a single form, as in:
> <field name="foo">lat lon</field>
