solr 4.0中的mergeFactor用法

我认为mergeFactor可以被认为是段中的最大数量,但是当它设置为10时,我在索引之后得到16个段,并且当段的数量超过15和20时发生合并.我真的很困惑mergeFactor的意思.

这是我的配置

<ramBufferSizeMB>32</ramBufferSizeMB>
<maxBufferedDocs>100000</maxBufferedDocs>
<mergeFactor>10</mergeFactor>

SolrCore java.io.FileNotFoundException

我在索引时偶尔会遇到异常FileNotFoundException，但并不是每次都会发生。有人有一些线索吗？这是回溯：
