从Apache solr中提取内容摘录

Question

我已经为我的Mysql表使用了Solr和search.Now，我希望从匹配的结果中获取摘录，并对其进行高亮处理。我必须在哪里进行更改？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>



       <str name="v.template">browse</str>
       <str name="v.layout">layout</str>
       <str name="title">Solritas</str>

       <str name="defType">edismax</str>
       <str name="q.alt">*:*</str>
       <str name="rows">10</str>
       <str name="fl">*,score</str>
       <str name="mlt.qf">
         text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
       </str>
       <str name="mlt.fl">text,features,name,sku,id,manu,cat</str>
       <int name="mlt.count">3</int>

       <str name="qf">
          text^0.5 features^1.0 name^1.2 sku^1.5 id^10.0 manu^1.1 cat^1.4
       </str>

       <str name="facet">on</str>
       <str name="facet.field">cat</str>
       <str name="facet.field">manu_exact</str>
       <str name="facet.query">ipod</str>
       <str name="facet.query">GB</str>
       <str name="facet.mincount">1</str>
       <str name="facet.pivot">cat,inStock</str>
       <str name="facet.range">price</str>
       <int name="f.price.facet.range.start">0</int>
       <int name="f.price.facet.range.end">600</int>
       <int name="f.price.facet.range.gap">50</int>
       <str name="f.price.facet.range.other">after</str>
       <str name="facet.range">manufacturedate_dt</str>
       <str name="f.manufacturedate_dt.facet.range.start">NOW/YEAR-10YEARS</str>
       <str name="f.manufacturedate_dt.facet.range.end">NOW</str>
       <str name="f.manufacturedate_dt.facet.range.gap">+1YEAR</str>
       <str name="f.manufacturedate_dt.facet.range.other">before</str>
       <str name="f.manufacturedate_dt.facet.range.other">after</str>



       <!-- 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>
     </lst>
     <arr name="last-components">
       <str>spellcheck</str>
     </arr>
     <!--
     <str name="url-scheme">httpx</str>
     -->
  </requestHandler>

Answer 1

您需要更改以下配置以启用高亮显示，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配置用于突出显示的每个参数。
