I am using following query to fetch all last 30 minutes records using elastic search, but I'm getting parsable error on line "now-30m".
Query:
{
"query": {
"bool": {
"must": [
{
"match": {
"appName": "magnus-alerting-system"
}
},
{
"match": {
"countryCode": "US2"
}
},
{
"match": {
"eventCode": 201
}
},
{
"match": {
"extractName": "LaborDemand"
}
},{
"range": {
"eventPostTimestamp": {
**"gte": "now()-30m"**
}
}
}
]
}
}
}
执行服务时邮递员出错: “根本原因”: [ { “ type”:“ number_format_exception”, “ reason”:“对于输入字符串:\” now()-30m \“” } ]
请让我知道如何纠正它。

原因是因为elasticsearch中的now()-30m错误,因为正确的格式只是“ now”。 Documentation
因此,正确的查询如下:
{
"query": {
"bool": {
"must": [
{
"match": {
"appName": "magnus-alerting-system"
}
},
{
"match": {
"countryCode": "US2"
}
},
{
"match": {
"eventCode": 201
}
},
{
"match": {
"extractName": "LaborDemand"
}
},{
"range": {
"eventPostTimestamp": {
"gte": "now-30m"
}
}
}
]
}
}
}

在data math中使用range query for date field的正确语法如下:
{
"range": {
"eventPostTimestamp": {
"gte": "now-30m"
}
}
}
