ElasticSearch NEST多重匹配返回所有结果

问题描述

我有这个C＃代码，预期使用multi-match弹性搜索类型来匹配2个字段。我正在使用nesT软件包。

var response = await _elasticclient.SearchAsync<FileDocument>(
     s => s.Query(q => q.MultiMatch(c => c
     .Fields(f => f.Field(p => p.FileName).Field(query))
     .Fields(f => f.Field(p => p.Metadata).Field(query))
     )));

无论我传入什么文本，问题都将返回所有结果。我有什么想念的吗？

解决方法

为了有效地调试这些类型的问题，您需要检查去往Elasticsearch的HTTP请求，最终您的查询生成器将转换为 search JSON 并将针对Elasticsearch执行。

我不知道nest，但是已经为Java代码编写了answer，该代码以JSON格式打印Elasticsearch查询。

尽管我的猜测是，您没有发送正确的HTTP方法，该方法应该为POST，并且可能与GET发送，这导致ES忽略搜索查询并返回所有文档。

添加lst1 <- strsplit(gsub("\t","",lines[c(FALSE,TRUE)]),"") lst1 #[[1]] # [1] "D" "M" "E" "S" "P" "V" "F" "A" "F" "P" "K" "A" "L" "D" "L" "E" "T" "H" "I" "E" "K" "L" "F" "L" "Y" #[[2]] # [1] "D" "D" "T" "L" "D" "D" "S" "D" "E" "D" "D" "I" "V" "V" "E" "S" "Q" "D" "P" "P" "L" "P" "S" "W" "G" #[[3]] # [1] "P" "R" "R" "E" "T" "E" "E" "F" "N" "D" "L" "K" "A" "L" "D" "F" "I" "L" "S" "N" "S" "L" "T" "H" "P" #[[4]] # [1] "E" "K" "A" "R" "M" "I" "Y" "E" "D" "D" "E" "T" "Y" "L" "S" "P" "K" "E" "V" "S" "L" "D" "S" "R" "V"

后已解决
