地理多边形查询
编辑地理多边形查询
编辑在 7.12 版中已弃用。
请改用 Geoshape，其中多边形以 GeoJSON 或 Well-Known Text (WKT) 定义。
返回仅落在点多边形内的匹配结果的查询。以下是一个示例
resp = client.search(
query={
"bool": {
"must": {
"match_all": {}
},
"filter": {
"geo_polygon": {
"person.location": {
"points": [
{
"lat": 40,
"lon": -70
},
{
"lat": 30,
"lon": -80
},
{
"lat": 20,
"lon": -90
}
]
}
}
}
}
},
)
print(resp)
const response = await client.search({
query: {
bool: {
must: {
match_all: {},
},
filter: {
geo_polygon: {
"person.location": {
points: [
{
lat: 40,
lon: -70,
},
{
lat: 30,
lon: -80,
},
{
lat: 20,
lon: -90,
},
],
},
},
},
},
},
});
console.log(response);

允许的格式
编辑经纬度作为数组
编辑格式为 [lon, lat]
注意：此处经度/纬度的顺序必须符合 GeoJSON。
resp = client.search(
query={
"bool": {
"must": {
"match_all": {}
},
"filter": {
"geo_polygon": {
"person.location": {
"points": [
[
-70,
40
],
[
-80,
30
],
[
-90,
20
]
]
}
}
}
}
},
)
print(resp)
const response = await client.search({
query: {
bool: {
must: {
match_all: {},
},
filter: {
geo_polygon: {
"person.location": {
points: [
[-70, 40],
[-80, 30],
[-90, 20],
],
},
},
},
},
},
});
console.log(response);
GET /_search

经纬度作为字符串
编辑格式为 lat,lon。
resp = client.search(
query={
"bool": {
"must": {
"match_all": {}
},
"filter": {
"geo_polygon": {
"person.location": {
"points": [
"40, -70",
"30, -80",
"20, -90"
]
}
}
}
}
},
)
print(resp)
const response = await client.search({
query: {
bool: {
must: {
match_all: {},
},
filter: {
geo_polygon: {
"person.location": {
points: ["40, -70", "30, -80", "20, -90"],
},
},
},
},
},
});
console.log(response);

geo_point 类型
编辑查询 需要在相关字段上设置 geo_point 类型。
忽略未映射
编辑当设置为 true 时，ignore_unmapped 选项将忽略未映射的字段，并且不会为该查询匹配任何文档。这在查询可能具有不同映射的多个索引时非常有用。当设置为 false（默认值）时，如果字段未映射，则查询将引发异常。
