Solr v6.6.3使用自定义searchHandler时抛出IOexception

标签： solr solrj solr6

我已经在Linux OS上安装并配置了SOLR 6.6.3。并配置了DIH和一个名为filesearch的搜索处理程序，该处理程序的简单碎片为locolhost:8983/solr/fI_idx。但是使用该配置的搜索处理程序进行搜索时会出现问题。从查询部分的Admin UI中，如果在请求处理程序中使用/select运行，则能够获取在本地服务器中索引的结果，但是当我尝试将filesearch作为请求处理程序和搜索传递时它给

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，为什么当您使用默认/select时尝试使用新的searchHanlder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>

正在观察的主要问题是因为oldserver中的luceneMatchVersion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，使用DIH进行索引。然后尝试使用filesearch进行搜索，但无法正常工作的是完整错误

如下修改了searchHandler并解决了该问题。由于版本升级，需要进行修改。 

<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>
