从 Apache solr 中提取内容摘录

Question

我已将 Solr 用于 Mysql 表以进行索引和搜索。现在我想从匹配的结果中摘录并突出显示它。 我必须在哪里进行更改 在这里吗？如果是，是什么？

<requestHandler name="/browse" class="solr.SearchHandler">
     <lst name="defaults">
       <str name="echoParams">explicit</str>

       <!-- VelocityResponseWriter settings -->
       <str name="wt">velocity</str>

Answer 1

您需要更改以下配置以启用突出显示并指定需要启用它们的字段。

   <!-- Highlighting defaults -->
   <str name="hl">on</str>
   <str name="hl.fl">text features name</str>
   <str name="f.name.hl.fragsize">0</str>
   <str name="f.name.hl.alternateField">name</str>

检查HighlightingParameters，它将详细说明您可以为突出显示配置的每个参数。
