java - 错误未定义字段 : "language"

Question

我有一个使用 apache solr (版本 6.2)和 tika 的项目。我配置了 schema.xml、data-config.xml 和 solrconfig.xml，但是当我尝试使用方法\update\extract\上传 pdf 时，日志显示错误。

错误:

 Status: failure
Response:
{
  "responseHeader": {
    "status": 400,
    "QTime": 1664
  },
  "error": {
    "metadata": [
      "error-class",
      "org.apache.solr.common.SolrException",
      "root-error-class",
      "org.apache.solr.common.SolrException"
    ],
    "msg": "undefined field: \"language\"",
    "code": 400
  }
}

这个 Java 错误:

org.apache.solr.common.SolrException: undefined field: "language"

有人可以帮助我吗？

检查 schema.xml 文件是否缺少语言字段及其类型定义。将语言字段添加到架构文件中。示例:

<field name="language" type="text_english" indexed="true" stored="true"/>

text_english 的字段定义

<fieldType name="text_english" class="solr.TextField" positionIncrementGap="100">
<analyzer>
<tokenizer class="solr.StandardTokenizerFactory"/>
<filter class="solr.StopFilterFactory" ignoreCase="true" words="lang/stopwords_en.txt"/>
<filter class="solr.LowerCaseFilterFactory"/>
</analyzer>
</fieldType>
