最近开始研究elasticsearch例如添加geo_hash类型的坐标是这样的 filter {      mutate {          add_field => {"location" => "%{y},%{x}"}  --把x，y变为location属性，类型为geohash remove_field => ["@version","@timestamp","qsdwmc","gldwmc","bz","sjly","rksj","guid","clsj"," czsj","x","y","mjzrq","gxsj"]     }  }   但是我看了官网上的例子：  PUT /example {     "mappings": {         "doc": {             "properties": {                 "location": {                     "type": "geo_shape"                 }             }         }     } } POST /example/doc?refresh {     "name": "Wind & Wetter, Berlin, Germany",     "location": {         "type": "point",         "coordinates": [13.400544, 52.530286]     } }   请问各位大佬通过logstash怎么添加这样子的location的属性，type为point，然后还有个coordinates数组
