[英]how to perform search in elasticsearch query?
我想在弹性搜索上执行这样的查询=>
select * 来自 customerName = 'google' 和 Type = 'stackoverflow' 且 query_string 可以来自任何索引的订单。 (即查询字符串可以是 'google' 或 'stackoverflow' 或 'a' 或 'b' 或 'c ' 或 'd'
table orders:
customerName type column1 column2 column3 column4
google stackoverflow a b c d
apple stackoverflow a b c d
google stackoverflow a b c d
microsoft stackoverflow a b c d
expected output:
google stackoverflow a b c d
google stackoverflow a b c d
即第1行和第3行
我试过用
"query": {
"bool": {
"must": {
"multi_match": {
"query": "b"
}
},
"filter": {
"terms": {
"customerName": [ "google" ],
"type": [ "stackoverflow ]
}
}
}
}
请帮忙:)
似乎您在查询中缺少 fields(column) 标记。 假设来自关系表格式的模式,查询应该是
{
"query": {
"bool": {
"must": {
"multi_match": {
"query": "b",
"fields": [
"column1",
"column2",
"column3",
"column4"
]
}
},
"filter": {
"terms": {
"customerName": [
"google"
],
"type": [
"stackoverflow"
]
}
}
}
}
}
添加包含索引数据、搜索查询和搜索结果的工作示例
指数数据:
{
"customerName": "google",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
{
"customerName": "apple",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
{
"customerName": "google",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
{
"customerName": "microsoft",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
搜索查询:
{
"query": {
"bool": {
"filter": [
{
"term": {
"customerName": "google"
}
},
{
"term": {
"type": "stackoverflow"
}
}
],
"must": {
"multi_match": {
"query": "a",
"fields": [
"customerName",
"type",
"column1",
"column2",
"column3",
"column4"
]
}
}
}
}
}
搜索结果:
"hits": [
{
"_index": "stof_63988272",
"_type": "_doc",
"_id": "1",
"_score": 0.10536051,
"_source": {
"customerName": "google",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
},
{
"_index": "stof_63988272",
"_type": "_doc",
"_id": "3",
"_score": 0.10536051,
"_source": {
"customerName": "google",
"type": "stackoverflow",
"column1": "a",
"column2": "b",
"column3": "c",
"column4": "d"
}
}
