我已经安装了solr 6.4，并且我很困惑下面的错误消息，并且在索引了几条记录之后，我的solr服务器已停止。
WARN (coreLoadExecutor-6-thread-1) [ x:MCI] o.a.s.s.FieldTypePluginLoader TokenFilterFactory is using deprecated 5.0.0 emulation. You should https://stackoverflow.com/questions/41960270/fulfill-deprecated-updating-to-protractor-5-0-0at some point declare and reindex to at least 6.0, because 5.x emulation is deprecated and will be removed in 7.0
任何帮助都会有所帮助。 谢谢
