autosuggest - 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，但我收到一条错误消息

"No suggester named default was configured" when I type ../../suggest?suggest.q=A&wt=json&suggest.build=true&indent=true&debugQuery=true in the browser

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“字典”参数添加到您的请求处理程序默认参数中，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:

如果您尚未在请求处理程序默认参数中指定“字典”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>

然后您可以使用以下网址:

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