Solr v6.6.3 在使用自定义 searchHandler 时抛出 IOexception
Solr v6.6.3 throwing IOexception while using custom searchHandler
我已经在 linux OS 上安装并配置了 SOLR 6.6.3。并配置了 DIH 和名为 filesearch 的搜索处理程序，它具有简单的分片 locolhost:8983/solr/fI_idx。但是在使用配置的搜索处理程序进行搜索时出现问题。如果 运行 在请求处理程序中使用 /select，则来自查询部分的管理员 UI 我能够获得在本地服务器中编制索引的结果，但是当我尝试传递 filesearch 作为请求处理程序和搜索它给出
null:org.apache.solr.common.SolrException:
org.apache.solr.client.solrj.SolrServerException: IOException occured
when talking to server at: http://localhost:8983/solr/FI_idx
27/06/2018, 15:45:12
ERROR true
谁能告诉我可能是什么问题。您可能会问一个问题，为什么在默认情况下需要新的 searchHanlder /select 我正在尝试将其作为分布式搜索功能的一部分。
/filesearch
的定义
<requestHandler name="/filesearch" class="solr.SearchHandler">
<lst name="defaults">
<str name="q.alt">*:*</str>
<str name="shards">localhost:8983/solr/FI_idx</str>
<str name="df">document</str>
</lst>
</requestHandler>
我观察到的主要问题是因为 luceneMatchVersion 在旧服务器中是 LUCENE_40 现在我在更改版本后将其更改为 LUCENE_CURRENT 或 6.6.3通过从数据库中提取记录来使用 DIH 进行索引。然后尝试使用 filesearch 进行搜索，但它不起作用，下面是完整的错误

如果需要任何其他信息，请告诉我。
谢谢。
如下修改searchHandler并解决了问题。由于版本升级需要修改。
<requestHandler name="/filesearch" class="solr.SearchHandler">
<lst name="defaults">
<str name="q.alt">*:*</str>
<str name="shards">localhost:8983/solr/FI_idx</str>
<str name="df">document</str>
<str name="shards.qt">/select</str>
</lst>
</requestHandler>
对搜索处理程序的额外更改是
<str name="shards.qt">/select</str>
请在此处找到有关讨论的更多详细信息
