【ES】同时使用should和must 导致只有must生效
参数如下:
{
"size": 10000,
"query": {
"bool": {
"must": [
{
"range": {
"dateTime": {
"from": "2022-09-21",
"to": "2022-09-22",
"include_lower": true,
"include_upper": true,
"boost": 1.0
}
}
}
],
"should": [
{
"match": {
"device": "01223344"
}
}
]
}
}
}
通过查询,should 是不生效的。
解决方案
解决方案一:加上"minimum_number_should_match": 1 这个设置should语句的满足条件值。
解决方案二:将should嵌在must语句中。
方案一:
{
"size": 10000,
"query": {
"bool": {
"must": [
{
"range": {
"dateTime": {
"from": "2022-09-21",
"to": "2022-09-22",
"include_lower": true,
"include_upper": true,
"boost": 1.0
}
}
}
],
"should": [
{
"match": {
"device": "01223344"
}
}
]
"minimum_should_match": 1
}
}
}
方案二:
{
"query": {
"bool": {
"must": [
{
"range": {
"dateTime": {
"from": "2022-09-20T23:30:00",
"to": "2022-09-21"
}
}
},
{
"bool": {
"should": [
{
"term": {
"device": "01223344"
}
}
]
}
}
]
}
}
}
