Question

我无法从solr索引中搜索名为doc_id的特定字段。我得到的数据来自DB2，而doc_id是表中的PK。

这里是数据导入和架构xml

请帮忙

SQL非常直观 - 来自此的各种SQL结果将包含像“d.DOC_ID”或“ann.doc_id”这样的列...而不是像Solr架构中的“doc_id”。

在某些SQL字段中，您确实有“as customer”之类的内容，这意味着这些特定字段将正常工作，假设整个文档通过验证 - 标记为required（或uniqueKey）的字段都存在，等

您可能需要在select语句中为每个字段添加“AS xxx”。

如果要搜索使用“as”语法的字段，请注意它们中的大多数都设置为键入“string”。在示例模式中，“string”类型是StrField，它没有分析功能，因此只能进行精确的整个字段或通配符匹配。您不能使用StrField类型搜索多字符串中的单个单词。
