solr 5.3 - 建议功能不起作用

Question

我在solrconfig.xml文件中添加了搜索组件和请求处理程序,但是我收到错误消息

当我../../suggest?suggest.q=A&wt=json&suggest.build=true&indent=true&debugQuery=true在浏览器中输入时,"没有配置名为default的建议者"

Answer 1

假设您的搜索组件是:

<searchComponent name="suggest" class="solr.SuggestComponent">
 <lst name="suggester">
   <str name="name">mySuggester</str>
             ...
 </lst>

第一种方式:

您必须将"dictionary"参数添加到请求处理程序默认参数,如下所示:

<requestHandler name="/suggest" class="solr.SearchHandler">
 <lst name="defaults">
   <str name="suggest.dictionary">mySuggester</str>
   <str name="suggest">true</str>
   <str name="suggest.count">10</str>
 </lst>
 <arr name="components">
   <str>suggest</str>
 </arr>
</requestHandler>

第二种方式:

如果未在请求处理程序默认参数中指定"dictionary"参数,则必须将其添加到URL.

例如:

<requestHandler name="/suggest" class="solr.SearchHandler">
 <lst name="defaults">
   <str name="suggest">true</str>
   <str name="suggest.count">10</str>
 </lst>
 <arr name="components">
   <str>suggest</str>
 </arr>
</requestHandler>

然后你可以使用以下网址:

../../suggest?suggest.dictionary=mySuggester&q=A&wt=json&suggest.build=true&indent=true&debugQuery=true
