`src/main/config/schema`.
Ambari will eventually install these, but at the moment it's manual and
you should refer to the Solr documentation
[https://lucene.apache.org/solr/guide/6_6](here) in general
and

if you'd like to know more about schemas in Solr.

+In Metron's Solr DAO implementation, document updates involve reading a
document, applying the update and reindexing the whole document.
+Indexing LatLon and PointType field types stores data in internal fields
that should not be returned in search results. For these fields a dynamic
field type matching the suffix needs to be added to store the data points.

We went through a lot of discussion on this PR to figure out the exact
fields and versions of Solr that the LatLon and Point types are problematic
for. Can you be a bit more explicit about that here? It's not just "for
example" it's literally "these types are a problem bc \<link to problem\> in
Solr version X.X, but have been corrected in Solr version X.Y"
