由于analyzer没有设置JSON格式的访问权限，我无法确认，但最可能的问题是您的搜索分析器autocomplete\u search
正在创建与索引时间标记匹配的搜索时间标记
例如：您正在搜索TR000002_1_2020
，如果它创建2020
作为标记，并且对于包含TR000011_1_2020
的文档，也会创建一个2020
标记，而您的查询将与之匹配
您可以使用来检查基于分析器生成的令牌，如前所述，大部分令牌是匹配的，如上图所示。如果您说返回所有结果，您可以更具体一些，您应该在结果中提供一些示例文档、预期文档和当前文档，我已经多次使用过这个查询，它是有效的。@OpsterElasticsearchNinja添加了一个编辑，向您显示返回的数据样本（27个中的3个）。testRecordId
属性很重要。我还添加了index/_映射
GET来显示它正在使用分析器。我还能为您提供什么帮助？谢谢编辑：还添加了我如何使用kibana控制台测试结果，非常清楚，我知道为什么会出现这个问题，但要确认，我需要查看JSON格式的索引设置，您可以使用设置API来提供吗？@opterElasticSearchNinja我添加了一个编辑来显示\u设置
响应，如果有帮助的话。到目前为止非常感谢：）是的，根据analyze
API，这正是正在发生的事情！根据您的经验，对于这样的搜索场景，您倾向于使用什么方法？我是否必须将结果转换为通配符？使用通配符是我的第一次尝试，但由于通配符查询的大小写敏感，所以我遇到了一些问题keyword@JordanLewallen这是后续问题，您已经测试了analyzer API的O/P，并确认这是由于analyzer的不正确使用造成的，我希望你能投票，接受答案，并提出一个新的问题，这个问题集中在搜索用例上，这样一来，这两篇文章都会有重点，对社区有帮助：）@JordanLewallen也请在你有了新问题的链接后马上打电话给我，我会尽快为你提供有效的解决方案：）好的观点，在这里创建了一个新问题：将此问题标记为正确！非常感谢迄今为止的帮助
