我在Solr 7.5安装中收到一些弃用警告：

[ WARN] 16:38:36  Solr loaded a deprecated plugin/analysis class [solr.TrieFloatField]. Please consult documentation how to replace it accordingly. []

[ WARN] 16:38:37  Solr loaded a deprecated plugin/analysis class [solr.SynonymFilterFactory]. Please consult documentation how to replace it accordingly. []

documentation只是告诉我Trie *已过时，除以下内容外，我找不到迁移指南：

TrieDateField: Deprecated. Use DatePointField instead.

我可以只替换Trie *字段类型类并更新正在运行的Solr实例上的架构吗？

那这里提到的非Trie字段呢？

Answer 1

它们是否要更换，取决于您的使用情况，但是是的，它们应该做同样的事情，只是效率更高。不过，您必须在更改类型后重新索引-您不能只更改架构并假设现有数据将按预期工作（因为最终将使用不同的数据类型）在进行遍历文档的操作时）。

对于过滤器，它们已被对应的Graph（SynonymGraphFilter和WordDelimiterGraphFilter）取代。

LatLonType已替换为LatLonPointSpatialField。

您可以看到这些changes in Major Changes in Solr 7的列表。

如果在架构中使用Trie *字段，则应考虑尽快迁移到PointFields。更改为新的PointField类型将需要您重新索引数据。

Solr的DatePointField是否可以替代TrieDateField？
