我正在使用Solr 3.6.1，我非常满意。现在我想继续使用solr4.1。所以我使用了“schema.xml”和“solrconfig.xml”（稍作修改）并将它们放在我的新solr4.1配置下。索引成功（DIH）。但是，我注意到了一个问题。在“schema.xml”中，我有“copyField”指令，以便使用不同的“类型”索引相同的字段。当我尝试使用solr4.1上的相同配置进行索引时，索引大小是solr3.6.1上索引大小的一半（当我查询时得到不同的结果）。 Solr4.1有什么变化吗？我对此一点帮助。

Solr 4.1以压缩的方式维护存储的字段，这可以解释索引大小的减少。
另外，
<copyField source="content" dest="contentS" />
文档@ http://wiki.apache.org/solr/SchemaXml#Copy_Fields
副本在流源级别完成，没有副本反馈到另一个副本。
将copyfield作为copyfield标记的来源不起作用 复制域源必须是实际字段，它具有一些值并且不会级联。
您还可以查看http://lucene.472066.n3.nabble.com/does-copyField-recurse-td2450208.html
这对你有用吗？
