请在下面找到我的文件名字段的映射查询。
PUT /articles
{
"settings" : {
"analysis" : {
"analyzer" : {
"filename_search" : {
"tokenizer" : "filename",
"filter" : ["lowercase"]
},
"filename_index" : {
"tokenizer" : "filename",
"filter" : ["lowercase","edge_ngram"]
}
},
"tokenizer" : {
"filename" : {
"pattern" : "[^\\p{L}\\d]+",
"type" : "pattern"
}
},
"filter" : {
"edge_ngram" : {
"side" : "front",
"max_gram" : 50,
"min_gram" : 1,
"type" : "edgeNGram"
}
}
}
},
"mappings" : {
"doc" : {
"properties" : {
"filename" : {
"type" : "text",
"search_analyzer" : "filename_search",
"analyzer" : "filename_index"
}
}
}
}
}
如果我尝试查询series1333372 doc623258并且期待karthik_series1333372_oracle_page_doc623258_v1_en-EU.pdf。但它提供了所有具有 series1333372 的文件，甚至没有检查 doc623258。
请在下面找到我的查询
get articles/_search
{
"query" : {
"match" : {
"filename" : "series1333372 doc623258"
}
}
}
我插入以下示例文档以从 Kibana 进行测试
POST articles/doc/1
{
"filename" : "karthik_series1333372_oracle_page_doc623258_v1_en-EU.pdf"
}
POST articles/doc/2
{
"filename" : "karthik_series1333372_sun_page_doc658_v1_en-EU.pdf"
}
POST articles/doc/3
{
"filename" : "series1333372_oracle_page_doc623_v1_en-US.pdf"
}
POST articles/doc/4
{
"filename" : "Engineering series1333372 valve_page doc6232 v1_en-US.pdf"
}
POST articles/doc/5
{
"filename" : "Machines_series1333372_page_doc62258_v1_en-US.pdf"
}
POST articles/doc/6
{
"filename" : "AIX series1333372 IBM page doc62358 v1_en-EU.pdf"
}
最佳答案
match的默认运算符是OR。如果您希望所有条款都存在，请像这样更改
GET articles/_search
{
"query" : {
"match" : {
"filename" : {
"query": "series1333372 doc623258",
"operator" : "and"
}
}
}
}
关于java - Elasticsearch 结果与我的映射字段查询不太准确，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50838887/
