elasticsearch,mongoosastic,Node.js,Node.js 如何在elasticsearch中对地理坐标应用过滤器？
我正在使用elasticsearch和Mongoostic npm模块。我正在尝试对具有以下模型结构的地理坐标应用过滤器Node.js 如何在elasticsearch中对地理坐标应用过滤器？,node.js,

我的问题有了答案 映射 PUT/geo_测试

"mappings": {
"type_test": {
"properties": {
"name": {
"type": "string"
},
"geoLocation": {
"type": "nested",
"properties": {
"coordinates": {
"type": "geo_point",
"lat_lon": true
}
}
}
}
}
}
}
{
"query": {
"filtered": {
"filter": {
"nested": {
"path": "geoLocation",
"query": {
"filtered": {
"filter": {
"geo_distance": {
"distance": 5,
"distance_unit": "km",
"geoLocation.coordinates": {
"lat": 41.12,
"lon": -71.34
}
}
}
}
}
}
}
}
}
}
在您的查询中，只需使用
“geoLocation”“geoLocation.coordinates”
