Apache Solr 9.0 Django 4.0

Answer 1

latlonType自Solr 7以来已被弃用，现在已在Solr 9中删除。

使用 latlonpointspatialfield 。

＆lt; fieldType name =“位置” class =“ solr.latlonpointspatialfield” docvalues =“ true”/＆gt;

llpsf支持切换索引，存储，docvalues和Multivaled。启用“索引”（默认值）时，LLPSF内部使用二维Lucene“ Point”（BDK树）索引。当启用“ docvalues”时，纬度和纵向对被咬合成64位，并放入Lucene Docvalues中。 DocValues数据的准确性大约是一厘米。
