1. 创建mapping并插入数据
PUT /hotel_app
{
"mappings": {
"hotels": {
"properties": {
"pin": {
"properties": {
"location": {
"type": "geo_point"
}
}
}
}
}
}
}PUT /hotel_app/hotels/1
{
"name": "喜来登大酒店",
"pin" : {
"location" : {
"lat" : 40.12,
"lon" : -71.34
}
}
}
2. 在指定范围以内的搜索
GET /hotel_app/hotels/_search
{
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"filter": {
"geo_bounding_box": {
"pin.location": {
"top_left" : {
"lat" : 40.73,
"lon" : -74.1
},
"bottom_right" : {
"lat" : 40.01,
"lon" : -71.12
}
}
}
}
}
}
}
GET /hotel_app/hotels/_search
{
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"filter": {
"geo_polygon": {
"pin.location": {
"points": [
{"lat" : 40.73, "lon" : -74.1},
{"lat" : 40.01, "lon" : -71.12},
{"lat" : 50.56, "lon" : -90.58}
]
}
}
}
}
}
}
3. 附近xx米以内的点
GET /hotel_app/hotels/_search
{
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"filter": {
"geo_distance": {
"distance": "200km",
"pin.location": {
"lat": 40,
"lon": -70
}
}
}
}
}
}
4. 聚合函数
GET /hotel_app/hotels/_search
{
"size": 0,
"aggs": {
"agg_by_distance_range": {
"geo_distance": {
"field": "pin.location",
"origin": {
"lat": 40,
"lon": -70
},
"unit": "mi",
"ranges": [
{
"to": 100
},
{
"from": 100,
"to": 300
},
{
"from": 300
}
]
}
}
}
}
