我使用 fscrawler 2.3-SNAPSHOT 对文件夹“/tmp/es”中的文档进行了索引。它将它们映射为:
{
"properties" : {
"attachment" : {
"type" : "binary",
"doc_values": false
},
"attributes" : {
"properties" : {
"group" : {
"type" : "keyword"
},
"owner" : {
"type" : "keyword"
}
}
},
"content" : {
"type" : "text"
},
"file" : {
"properties" : {
"content_type" : {
"type" : "keyword"
},
"filename" : {
"type" : "keyword"
},
"extension" : {
"type" : "keyword"
},
"filesize" : {
"type" : "long"
},
"indexed_chars" : {
"type" : "long"
},
"indexing_date" : {
"type" : "date",
"format" : "dateOptionalTime"
},
"last_modified" : {
"type" : "date",
"format" : "dateOptionalTime"
},
"checksum": {
"type": "keyword"
},
"url" : {
"type" : "keyword",
"index" : true
}
}
},
"object" : {
"type" : "object"
},
"meta" : {
"properties" : {
"author" : {
"type" : "text"
},
"date" : {
"type" : "date",
"format" : "dateOptionalTime"
},
"keywords" : {
"type" : "text"
},
"title" : {
"type" : "text"
},
"language" : {
"type" : "keyword"
}
}
},
"path" : {
"properties" : {
"encoded" : {
"type" : "keyword"
},
"real" : {
"type" : "keyword",
"fields": {
"tree": {
"type" : "text",
"analyzer": "fscrawler_path",
"fielddata": true
}
}
},
"root" : {
"type" : "keyword"
},
"virtual" : {
"type" : "keyword",
"fields": {
"tree": {
"type" : "text",
"analyzer": "fscrawler_path",
"fielddata": true
}
}
}
}
}
}
}
现在,我想在我的 C# 应用程序中使用 NEST 搜索它们,我能够通过...获取内容hit.source.content
但无法通过...获取文件hit.source.filename
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);
}
}
上面抛出 NULLException 但是当我用hit.Source.url
and注释行时运行hit.Source.filename
。
Kibana 将文件名字段显示为file.filename
,将 url 显示为file.url
,将内容显示为content
.
由于文件名嵌套在文件下,我无法检索它......请帮助卡在这里几天......
