我正在使用以下命令对 nutch 抓取的数据运行 solrindex：

bin/nutch solrindex <prep><code>http://127.0.0.1:8983/solr/ /app/hadoop/tmp/crawled_pages/crawldb -linkdb /app/hadoop/tmp/crawled_pages/linkdb /app/hadoop/tmp/crawled_pages/segments/*

我收到以下错误，我无法找到此问题的根本原因。

org.apache.solr.common.SolrException: ERROR: [doc=http://www.bbc.co.uk/portugueseafrica/arquivo/index.shtml] unknown field 'cache'

ERROR: [doc=http://www.bbc.co.uk/portugueseafrica/arquivo/index.shtml] unknown field 'cache'

有没有人遇到过类似的问题？

我不明白以下错误的根本原因是什么。

org.apache.solr.common.SolrException: ERROR: [doc=http://www.bbc.co.uk/portugueseafrica/arquivo/index.shtml] unknown field 'cache'

在 solr_xx_xx/example/solr/conf/schema.xml 中添加了以下行

<field name="cache" type="string" stored="true" indexed="false"/>

它工作得很好。
