elasticsearch 弹性搜索：使用字段时查询字符串的不同结果
elasticsearch 弹性搜索：使用字段时查询字符串的不同结果
我们有一个弹性搜索5.5设置。我们使用nest通过C执行查询 执行以下查询时： 我们得到了期望的结果：一个以数字作为标识符的结果 使用以下查询时： 我们没有结果 我们正在搜索的值位于字段SearchIdentifier中，其值为1-00917751 我们有一个名为final的自定义分析器 .Customfinal，cu=>cu .Tokenizerkeyword.Filtersnew列表{小写} 字段SearchIdentifier上未设置自定义分析器。我们尝试在其中添加空白标记器，但没有任何区别 当我们尝试使用查询S328搜索值S328-25时，另一个名为searchObjectNo的字段确实起作用。这些字段完全相同 有什么想法吗 另一个问题。在第一个查询中，当我们搜索不带引号的1-00917751时，我们会得到很多结果。但我们认为这是因为关键字标记器 多谢各位 斯科夫 索引设置和映射：

答案很简单：在映射中，您的字段名为searchIdentifier，在查询中，您使用的字段名为searchIdentifier，但该字段不存在- 查看索引设置和映射会有所帮助。请用从curl-XGET localhost:9200获得的信息更新您的问题/yourindex@Val：我们在windows环境中托管弹性搜索，我认为windows？Powershell；-否则从Kibana得到你-index@Val补充说，谢谢！：@对于curl，您可以使用针对Linux WSL的Windows子系统。如果您想在PowerShell中获得类似的体验，请看一看，这确实解释了一部分！如果我现在搜索00917751，我会得到一个结果。搜索917751不会给出结果。有什么想法吗当不使用字段时，也会出现同样的问题。所以这个问题实际上已经解决了。另一个线程将给你一些想法：提示：使用ngramsI我不确定我是否理解这个建议。是否建议使用多个查询？我对此提出了一个单独的问题：不，如果您想使用ngramsI添加的nGram标记器高效地搜索输入前缀、中缀、后缀搜索的部分，那么您需要在索引时以不同的方式分析数据。但这对我的查询没有影响：仍然找到相同的结果。
