我使用的是Solr 3.6.1，非常满意。现在我想继续 solr4.1。所以我采用了“schema.xml”和“solrconfig.xml”(稍作改动)并将它们放在我新的 solr4.1 配置下。索引编制成功 (DIH)。但是，我注意到一个问题。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。当我尝试在 solr4.1 上使用相同的配置进行索引时，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？我在这方面几乎不需要帮助。

最佳答案
Solr 4.1 以压缩方式维护存储字段，这可以解释索引大小的减少。
此外，
<copyField source="content" dest="contentS" />
文档@ http://wiki.apache.org/solr/SchemaXml#Copy_Fields
The copy is done at the stream source level and no copy feeds into another copy.
将复制域作为复制域标记的来源是行不通的。
copyfield 源必须是一个实际的字段，它有一些值并且没有级联。
您还可以检查http://lucene.472066.n3.nabble.com/does-copyField-recurse-td2450208.html
这对你有用吗？？
关于solr - Solr4.1 上的 CopyField 问题，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/14605847/
