es-head文档数量疑问，按照理解括号外面的是主分片的文档数量，括号里面的是主分片加副本文档数量

var line2 = closed ? "\u00A0" : ( "docs: " + (index.status && index.status.primaries && index.status.primaries.docs && index.status.total && index.status.total.docs ? index.status.primaries.docs.count.toLocaleString() + " (" + (index.status.total.docs.count + index.status.total.docs.deleted).toLocaleString() + ")" : "unknown" ) );
 
在浏览器里看看head的源码就知道勒
