创建索引:
PUT student
{
"mappings" : {
"properties" : {
"name" : {
"type" : "keyword"
},
"age" : {
"type" : "integer"
}
}
}
}
使用 _bulk
创建文档
POST _bulk
{ "index" : { "_index" : "student", "_id" : "1" } }
{ "name" : "张三", "age": 12}
{ "index" : { "_index" : "student", "_id" : "2" } }
{ "name" : "李四", "age": 10 }
{ "index" : { "_index" : "student", "_id" : "3" } }
{ "name" : "王五", "age": 11 }
{ "index" : { "_index" : "student", "_id" : "4" } }
{ "name" : "陈六", "age": 11 }
使用 from、size 时,一般会先排序。
示例1:按照 _id
升序排序,取第0个数据:
GET student/_search
{
"query": {
"match_all": {}
},
"sort": [
{
"_id": {"order" : "asc"}
}
],
"from": 0,
"size": 1
}
示例2:按照 _id
升序排序,取第1~2个数据:
GET student/_search
{
"query": {
"match_all": {}
},
"sort": [
{
"_id": {"order" : "asc"}
}
],
"from": 1,
"size": 2
}
示例3:按照 _id
降序排序,取第0个数据:
GET student/_search
{
"query": {
"match_all": {}
},
"sort": [
{
"_id": {"order" : "desc"}
}
],
"from": 0,
"size": 1
}
