{
"mappings": {
"properties": {
"title":{
"type":"text"
},
"tags":{
"type": "keyword"
}

rust
GET task8/_search
{
"query": {
"function_score": {
"query": {
"bool": {
"should": [
{
"match": {
"title": "my"
}
},
{
"match": {
"title": "me"
}
}
]
}
},
"functions": [
{
"filter": {
"term": {
"tags": {
"value": "romatic movies"
}
}
},
"weight": 2
}
],
"boost": "5",
"boost_mode": "multiply"
}
}
}
二、题目
对索引 task9 编写一个查询模板,并满足以下要求:
- 使用
a_01
参数查询a
字段 - 使用
start_date
和end_date
参数范围查询timestamp
字段 - 如果没有提供
end_date
参数,那么结束时间默认是现在 - 查询结果中
b
字段必须等于 active
使用 查询模板查询 2018年6月1日到现在的数据,a
字段包含关键字 aaa
rust
# 创建索引
PUT task9
{
"mappings": {
"properties": {
"a":{
"type": "text"
},
"b":{
"type": "keyword"
},
"timestamp":{
"type": "date"
}
}
}
}
# 写入数据
POST /task9/_bulk
{"index": {}}
{"a":"aaa AAA", "b":"active", "timestamp":"2021-11-11T11:21:21.000Z"}
{"index": {}}
{"a":"aaa AAA", "b":"active", "timestamp":"2022-11-11T11:21:21.000Z"}
{"index": {}}
{"a":"AAA", "b":"b", "timestamp":"2023-11-11T11:21:21.000Z"}
