/update

标准的update request handler，适用于XML，JSON，CSV或者JAVABIN文件类型

<requestHandler name="/update" class="solr.UpdateRequestHandler">
     <lst name="defaults">
        <str name="update.chain">uuid</str>
     </lst>      
</requestHandler>

/update/extract

除了以上标准文件之外的文件，可通过此配置来为文件建索引

依赖包

  <lib dir="../../dist/" regex="apache-solr-cell-d.*.jar" />
  <lib dir="../../contrib/extraction/lib" regex=".*.jar" />

常规配置

  <requestHandler name="/update/extract"
                  startup="lazy"
                  class="solr.extraction.ExtractingRequestHandler" >
      <lst name="defaults">
      <str name="xpath">/xhtml:html/xhtml:body/descendant:node()</str>
      <str name="capture">content</str>
      <str name="fmap.meta">attr_meta_</str>
      <str name="uprefix">attr_</str>
      <str name="lowernames">true</str>
      <str name="update.chain">uuid</str>
