一种度量聚合，用于计算包含字段的所有 geo_point 值的边界框。
例如：
# 定义索引
PUT /museums
{
"mappings": {
"properties": {
"location": {
"type": "geo_point"
}
}
}
}
# 新增并索引文档
POST /museums/_bulk?refresh
{"index":{"_id":1}}
{"location": "52.374081,4.912350", "name": "NEMO Science Museum"}
{"index":{"_id":2}}
{"location": "52.369219,4.901618", "name": "Museum Het Rembrandthuis"}
{"index":{"_id":3}}
{"location": "52.371667,4.914722", "name": "Nederlands Scheepvaartmuseum"}
{"index":{"_id":4}}
{"location": "51.222900,4.405200", "name": "Letterenhuis"}
{"index":{"_id":5}}
{"location": "48.861111,2.336389", "name": "Musée du Louvre"}
{"index":{"_id":6}}
{"location": "48.860000,2.327000", "name": "Musée d'Orsay"}
# 执行搜索
POST /museums/_search?size=0
{
"query" : {
"match" : { "name" : "musée" }
},
"aggs" : {
"viewport" : {
"geo_bounds" : {
"field" : "location",
"wrap_longitude" : true
}
}
}
}
上面的聚合演示了如何为所有博物馆(museum)的文档计算 location 字段的边界框。
上面的聚合的响应：
