【问题描述】：
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：
{ "query": { "bool": { "must": [ { "query_string": { "query": "00917751" } } ] } } }
我们得到了想要的结果：一个以数字为标识符的结果。
使用以下查询时：
{ "query": { "bool": { "must": [ { "query_string": { "query": "00917751", "fields": [ "searchReference", "searchIdentifier", "searchObjectNo", "searchBrand", "searchExtSerNo" ] } } ] } } }
我们没有得到任何结果。
我们正在搜索的值在字段 searchIndentifier 中，值为“1-00917751”。
我们有一个名为“final”的自定义分析器
.Custom("final", cu => cu .Tokenizer("keyword").Filters(new List() { "lowercase" }))
字段 searchIndentifier 上没有设置自定义分析器。我们尝试在其中添加空格标记器，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”的字段确实有效。这些字段完全相同。
这里有什么想法吗？
另一个问题。在第一个查询中，当我们搜索 1-00917751（不带引号）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？
谢谢

这将有助于查看您的索引设置和映射。请用您从
curl -XGET localhost:9200/yourindex得到的信息更新您的问题 -
@Val：我们在 windows 环境中托管弹性搜索，我认为 curl 在 windows 上不存在？
-
Powershell ;-) 否则来自 Kibana
GET you-index -
@Val 已添加，谢谢！ :)
-
@Schoof 用于 curl，您可以使用适用于 Linux 的 Windows 子系统 (WSL)。如果您想在 PowerShell 中获得类似体验，请查看 gist.github.com/russcam/7fbdbaa37e3dcb3fd3ee0aa54af3708c
