C# 使用fscrawler的ElasticSearch文件映射和在C中通过嵌套搜索文档#
我使用fscrawler 2.3-SNAPSHOT为文件夹“/tmp/es”中的文档编制了索引。它将它们映射为:C# 使用fscrawler的ElasticSearch文件映射和在C中通过嵌套搜索文档#,c#,wpf,elasticsearch,nest,fscrawler,C#,Wpf,elasticsearch,Nest,Fscrawler,我使用fscrawler 2.3-SNAPSHOT为文件夹“/tmp/es”中的文档编制了索引。它将它们映射为: { "properties" : { "attachment" : { "type" : "binary", "doc_values": false }, "attributes" : { "properties" : { "group" : { "type" : "keyword"

现在,我想在我的C#应用程序中使用NEST搜索它们,我可以通过hit.source.content
获取内容,但无法通过hit.source.filename
获取文件名
代码:
var response = elasticClient.Search<documents>(s => s
.Index("tanks")
.Type("doc")
.Query(q => q.QueryString(qs => qs.Query(query))));
if (rtxSearchResult.Text != " ")
{
rtxSearchResult.Text = " ";
foreach (var hit in response.Hits)
{
rtxSearchResult.Text = rtxSearchResult.Text + ("Name: " + hit.Source.fileName.ToString()
+ Environment.NewLine
+ "Content: " + hit.Source.content.ToString()
+ Environment.NewLine
+ "URL: " + hit.Source.url.ToString()
+ Environment.NewLine
+ Environment.NewLine);
}
}
var response=elasticClient.Search(s=>s
.索引(“储罐”)
.Type(“doc”)
.Query(q=>q.QueryString(qs=>qs.Query(Query)));
如果(rtxSearchResult.Text!=“”)
{
rtxSearchResult.Text=“”;
foreach(响应中的var hit.Hits)
{
rtxSearchResult.Text=rtxSearchResult.Text+(“名称:”+hit.Source.fileName.ToString()
+环境新线
+内容:“+hit.Source.Content.ToString()
+环境新线
+URL:+hit.Source.URL.ToString()
+环境新线
+环境(新线),;
}
}
上面的抛出NULLException,但在我使用hit.Source.url
和hit.Source.filename
注释行时运行
Kibana将文件名字段显示为file.filename
,url显示为file.url
,内容显示为content
由于文件名嵌套在文件下,我无法检索它…请帮助我在这里停留几天。发现错误:
我的文件课是:
Class documents
{
Public string filename { get; set; }
Public string content { get; set; }
Public string url { get; set; }
}
由于文件名和url分别为file.filename
和file.url
,我们需要另一个带有文件名和url的类文件
Class documents
{
Public File file { get; set; }
Public string content { get; set; }
}
Class File
{
Public string filename { get; set; }
Public string url { get; set; }
}
因此,我可以通过
hit.Source.file.filename
和hit.Source.file.url
访问它们,您的类型文档是什么样子的?你能给我看看吗?
