我具有以下文件夹结构，我的solr版本为8.6.3。 当我输入命令时：
solr/
├── bin/
├── CHANGES.TXT
├── contrib/
├── dist/
├── docs/
├── example/
├── licenses
............
├── server/
└── tempfolder/
└── index.html
我收到以下错误：
Solr针对网址返回了错误＃404（未找到）： http：// localhost：8983 / solr / solrhelp / update / extract？resource.name = / home / user / solr-8.6.3 / example / my-examples / index.html＆literal.id = / home / user / solr- 8.6.3 / example / my-examples / index.html
但是在solr-8.3.1中，此命令可以正常工作。 solr-8.6.3是否支持html文件索引？如果是，该怎么办？
解决方法
您有to enable the ExtractingRequestHandler and configure it可以使用/extract。这可能已经在您的旧安装中完成了。
如果您不使用示例配置集，则不会自动加载使用Solr Cell所需的jar。您将需要配置solrconfig.xml来找到ExtractingRequestHandler及其依赖项：
<lib dir="${solr.install.dir:../../..}/contrib/extraction/lib" regex=".*\.jar" /> <lib dir="${solr.install.dir:../../..}/dist/" regex="solr-cell-\d.*\.jar" />然后可以在solrconfig.xml中配置ExtractingRequestHandler。以下是Solr的_default configset中找到的默认配置，您可以根据需要进行修改：
<requestHandler name="/update/extract" startup="lazy" class="solr.extraction.ExtractingRequestHandler" > <lst name="defaults"> <str name="lowernames">true</str> <str name="fmap.content">_text_</str> </lst> </requestHandler>
