Solr MultiCore搜索(Solr MultiCore Search)

我正在使用Apache Solr进行搜索。 我用它来提供个人用户搜索。 即每个用户都有一个单独的物理Lucene索引。 所以对于10位用户，我在磁盘上有10个独立的物理索引。
为了支持这些索引的搜索，我打算使用Solr MultiCore Feature 。 随着我一直在阅读的各种文章，它看起来像这样工作。
我真的不知道的是，当一个solr搜索者得到一个查询，而不是将查询发送给所有多核时，我该如何将查询集中到具有该特定用户索引连接的核心？ 这是配置更改还是需要执行代码级别更改？
即我想发送查询只有一个solr核心（基于用户标识）。 这甚至有可能吗？
更新：根据其中一个解决方案，我可以在solrconfig.xml中添加多核，即在开始solr时，我需要提及核心（或者在我的情况下是用户）。 所以现在，如果我想添加一个新用户的索引，我可能需要停止solr，编辑其配置，添加该用户核心并再次启动solr。 有没有办法动态地将核心添加到正在运行的solr实例？

I am using Apache Solr for search. I use this to provide personal user-based search. i.e. each user has a separate physical Lucene Index. So for 10 users, I have 10 separate physical indexes on disk.
To support searches on these indexes, I am planning to use Solr MultiCore Feature. With the various articles I have been reading regarding this, it looks like this would work.
Where I am actually not sure is, when a solr searcher gets a query, instead of sending the query to all the multiple-cores, how do I funnel the query to that core which has that particular user's index connected to? Is this a config change or do I need to do code level changes?
i.e. I want to send the query to only one solr-core (based on userid). Is this even possible?
UPDATE: So according to one of the solutons I can add multi-cores in the solrconfig.xml i.e. at the time of starting solr I'll need to mention the cores (or in my case the users). So now, if I want to add a new user's index, I'll probably need to stop solr, edit its config, add that users core & start solr again. Is there any way to dynamically add cores to a running solr instance?

 尝试使用区分大小写整理来帮助您将密码与小写版本进行比较，如下所示：  
(len([PASSWORD])>(5) AND [PASSWORD] like '%[0-9]%' 
AND [PASSWORD] <> Lower([PASSWORD]) COLLATE Latin1_General_CS_AI)
 
 或者我自己的例子是这样的：  
Declare @Password varchar(20) = 'Hello'
if @Password <> Lower(@Password) COLLATE Latin1_General_CS_AI
    PRINT 'Upper'
else
    PRINT 'lower'

Try using a Case Sensitive Collation to help you out and compare password with a lower case version of it like below using your code: 
(len([PASSWORD])>(5) AND [PASSWORD] like '%[0-9]%' 
AND [PASSWORD] <> Lower([PASSWORD]) COLLATE Latin1_General_CS_AI)
 
Or my own example would be like this: 
Declare @Password varchar(20) = 'Hello'
if @Password <> Lower(@Password) COLLATE Latin1_General_CS_AI
    PRINT 'Upper'
else
    PRINT 'lower'
