Apache solr 使用分片分发搜索不起作用（shardsWhitelist）

Question

I have installed latest solr and creates multiple cores called Unicore and SAP core and as per the SOLR configurations of solr 8.7 distributed search we need to add the following code in the respective confgiurations directories solrconfig.xml file, below solrconfig.xml from Unicore conf

<requestHandler name="/select" class="solr.SearchHandler">
  <!-- other params go here -->
  <shardHandlerFactory class="HttpShardHandlerFactory">
    <int name="socketTimeout">1000</int>
    <int name="connTimeout">5000</int>
    <str name="shardsWhitelist">localhost:8983/solr/SAP</str>
  </shardHandlerFactory>
</requestHandler>

我用来从分片收集数据的查询：

http://localhost:8983/solr/UniCore/select?q=text:searchString&wt=json&indent=true&shards=localhost:8983/solr/SAP

发现以下问题：

我确实google了很多，但仍然无法找到解决方案。 参考stackverflow问题

Answer 1

Modfify solr.xml under solr server directory => update this file by adding core names into shardsWhitelist in the solsInstance\Server\solr\solr.xml and restart solr. 这适用于SOLR-8.7版本。

<!-- shardsWhiltlisting SAP core for distributed search -->

<shardHandlerFactory name="shardHandlerFactory"
    class="HttpShardHandlerFactory">
    <int name="socketTimeout">${socketTimeout:600000}</int>
    <int name="connTimeout">${connTimeout:60000}</int>
    <str name="shardsWhitelist">${solr.shardsWhitelist:hostName:8983/solr/SAP}</str> 
  </shardHandlerFactory>

为所有需要的核心配置 HttpShardHanldeFactory shardsWhiltlist

<str name="shardsWhitelist">${solr.shardsWhitelist:hostName:port/solr/core1,
hostName:port/solr/core2,.., solr.shardsWhitelist:hostName:port/solr/coren,}</str>
