Solr:DocValuesField在本文档中出现多次（Solr 6.5）

升级到Solr 6.5后，当我尝试将记录插入字段时，收到此错误

完全错误：

根据文档，

solr.LatLonType

不支持多值字段

<fieldType name="location" class="solr.LatLonPointSpatialField" docValues="true"/>

它出现在Solr6.5中，检查将多个值插入Solr.LatLonType的条件发生了变化

在Solr6.3中，我能够成功地将多个位置插入到

Solr.LatLonType

字段类型中

解决方案： 您应该将

位置

字段类型替换为

LatLonPointSpatialField

，这是支持多值字段的

solr.LatLonType

的替代品

<fieldType name="location" class="solr.LatLonPointSpatialField" docValues="true"/>
