@@ -95,3 +95,17 @@ As of now, we have mapped out the Schemas in
`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
[here](https://lucene.apache.org/solr/guide/6_6/documents-fields-and-schema-design.html)

+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.
+For example, a LatLongType field should be defined as:
+```
+<dynamicField name="*.location_point" type="location" multiValued="false"
docValues="false"/>
+<dynamicField name="*_coordinate" type="pdouble" indexed="true"
stored="false" docValues="false"/>
+<fieldType name="location" class="solr.LatLonType"
subFieldSuffix="_coordinate"/>
+```
+A PointType field should be defined as:
+```
+<dynamicField name="*._point" type="location" multiValued="false"
docValues="false"/>

> While testing [https://github.com/apache/metron/pull/970] I get this error
> when creating a meta alert:
> {code:java}
> Error from server at http://10.0.2.15:8983/solr/bro: Exception writing
> document id bbc150f5-92f8-485d-93cc-11730c1edf31 to the index; possible
> analysis error: DocValuesField
> \"enrichments.geo.ip_dst_addr.location_point_0_coordinate\" appears more than
> once in this document (only one value is allowed per field){code}
> I tracked it down to the fact that multiple fields are returned for a
> location field. For example when a field named
> "enrichments.geo.ip_dst_addr.location_point" is configured in a schema, these
> fields are returned in a query:
> {code:java}
> {
> "enrichments.geo.ip_dst_addr.location_point_0_coordinate": "33.4499",
> "enrichments.geo.ip_dst_addr.location_point_1_coordinate": "-112.0712",
> "enrichments.geo.ip_dst_addr.location_point": "33.4499,-112.0712"
> }
> {code}
> We need a way to either suppress these extra fields when querying or remove
> them before updating a document.
