当我尝试从 Solr 3.5 升级到 4.6 时遇到了这个错误。

原因：org.apache.solr.common.SolrException：默认搜索字段“名称”未定义或未编入索引。模式文件是 /opt/jetty/solr/./cores/core0/schema.xml at org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:608) at org.apache.solr.schema.IndexSchema.(IndexSchema.java:166) at org.apache.solr.schema.IndexSchemaFactory.create(IndexSchemaFactory.java:55) at org.apache.solr.schema.IndexSchemaFactory.buildIndexSchema(IndexSchemaFactory.java:69) at org.apache.solr.core.CoreContainer.createFromLocal(CoreContainer.java:554) at org.apache.solr.core.CoreContainer.create(CoreContainer.java:592) at org.apache.solr.core.CoreContainer$1.call(CoreContainer.java:271) at org.apache.solr.core.CoreContainer$1.call(CoreContainer.java:263) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) ... 还有 1 个原因： org.apache.solr.common.SolrException：默认搜索字段“name”未定义或未在 org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:507) 中编入索引... 还有 15 个，code=500}
在我的 schema.xml 上
<field name="name" type="text_general" indexed="true" stored="true" required="false" />
在我的 data-config.xml 上
<field column="name" name="name"/>
我已经尝试注释掉这些字段然后重新启动 jetty 服务器，但即使在日志文件上也没有出现特定的错误。
答案1
从 3.x 版到 4.x 版，Solr 改变了其 schema.xml 结构。在 4.x 版中，不再有 < types> 列表或 < fields>，只有 < type> 和 < field> 对象。
尝试注释 schema.xml 中的 < types></ /types> 和 < fields></fields> 标签对
希望有用！
