solr6.6 solrJ索引富文本(word/pdf)文件

　　1、文件配置

　　　　在core下面新建lib文件夹，存放相关的jar包，如图所示：

　　　　

　　　　

　　　　修改solrconfig.xml

　　　

<lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/clustering/lib/" regex=".*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-clustering-\d.*\.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/langid/lib/" regex=".*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-langid-\d.*\.jar" />

  <lib dir="${solr.install.dir:../../../..}/contrib/velocity/lib" regex=".*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-velocity-\d.*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
  <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
  <lib dir="./lib" regex=".*\.jar"/>

 

 

 

　　　　增加配置，如果有则不用添加：

　　　　

 <requestHandler name="/update/extract"
                  startup="lazy"
                  class="solr.extraction.ExtractingRequestHandler" >
    <lst name="defaults">
      <str name="fmap.content">text</str>
      <str name="fmap.meta">ignored_</str>
      <str name="lowernames">true</str>
      <str name="uprefix">attr_</str>
      <str name="captureAttr">true</str>
    </lst>
  </requestHandler>

 

 

 　　配置managed-schema文件：

　　　

　　

　　修改managed-schema文件，增加字段：

  <field name="path"      type="string"   indexed="true"  stored="true"  multiValued="false" />
  <field name="pathftype"      type="string"   indexed="true"  stored="true"  multiValued="false" />
  <field name="pathuploaddate"      type="string"   indexed="true"  stored="true"  multiValued="false" />
  <field name="pathsummary"      type="string"   indexed="true"  stored="true"  multiValued="false" />
  <field name="attr_content"      type="text_general"   indexed="true"  stored="true"  multiValued="false" />
