如何在SOLR云中指定搜索者和索引器？(How to designate searcher and indexer in SOLR cloud?)

 我目前有一个2节点solr（4.10.3）云集群，配置为1个分片，有2个副本（带3个节点的外部zookeeper集合）。 我怎样才能设置solr cloud来使用一个框进行搜索，一个框只用于索引？  
 它是否像将客户端指向其特定节点一样简单？  
 例如，如果我们有solr01（索引器）和solr02（搜索器）。 我们将所有客户端指向solr02何时执行搜索，以及所有客户端在需要添加新数据时指向solr01。 我可以看到的主要缺点是它会减少冗余。  
 有没有办法配置solr cloud来自动处理？ 

I currently have a 2 node solr (4.10.3) cloud cluster configured as 1 shard with 2 replicas (with a 3 node external zookeeper ensemble). How can I setup solr cloud to use one box just for searching, and one box just for indexing? 
Is it as simple as pointing clients to their specific nodes?  
For example if we have solr01(indexer) and solr02(searcher). We point all clients to solr02 when to perform a search, and all clients to solr01 when they need to add new data. The main downside that I can see to this is that it would reduce redundancy.  
Is there some way to configure solr cloud to do handle this automatically?

 从长度运算符来看，规则很简单：  
 
  除非给出__len元方法，否则仅在表是序列时定义表t的长度，即，对于某些非负整数n ，其正数字键的集合等于{1..n} 。 在这种情况下， n是它的长度。  
 
 在你的例子中：  
local myTab = {1,2,3,nil,5,nil,7}
 
 #mytab未定义，因为myTab不是序列，有或没有myTab["test"] = try 。  
local myT = {123,456,789}
 
 myT是一个序列，长度为3 ，有或没有myT["test"] = 10 

The rule is simple, from the length operator: 
 
 Unless a __len metamethod is given, the length of a table t is only defined if the table is a sequence, that is, the set of its positive numeric keys is equal to {1..n} for some non-negative integer n. In that case, n is its length.  
 
In your example: 
local myTab = {1,2,3,nil,5,nil,7}
 
#mytab is undefined because myTab isn't a sequence, with or without myTab["test"] = try. 
local myT = {123,456,789}
 
myT is a sequence, and the length is 3, with or without myT["test"] = 10
