我正在尝试将 mysql 数据（动态变化）与elasticsearch. 我logstash用于同步目的。我需要过滤 1KM 半径内的车辆列表为通过geo_points。在 elasticsearch 上进行 geo_point 查询时，出现以下错误：
{"error":
{"root_cause": [
{"type": "query_parsing_exception",
"reason": "failed to find geo_point field [location]",
"index":"current_location",
"line":13,
"col":9}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase":"query",
"grouped": true,
"failed_shards":[
{"shard":0,
"index": "current_location",
"node":"Pf8eXXX2QMuaskBuLSdcXw",
"reason": {
"type":"query_parsing_exception",
"reason":"failed to find geo_point field [location]",
"index":"current_location",
"line":13,
"col":9}}
]},
"status":400}
Curl我正在打的电话是：
curl -XGET http://MY.ELASTIC.SEARCH.IP:9200/current_location/vehicle/_search -d '
{
"query": {
"filtered": {
"filter": {
"geo_distance": {
"distance": "1km",
"distance_type": "plane",
"location": {
"lat": 40.715,
"lon": -73.988
}
}
}
}
}
}'
对任何索引的 curl 调用结果如下：
curl -XGET http://MY.ELASTIC.SEARCH.IP:9200/current_location/vehicle/XX12XX34XX56
{
"_index": "current_location",
"_type": "vehicle",
"_id": "XX12XX34XX56",
"_version": 1,
"found": true,
"_source": {
"obd_id": "XX12XX34XX56",
"system_timestamp": 1464855810,
"gps_timestamp": 1464855807,
"speed": 1.476,

"type": "vehicle",
"location": {
"lat": 12.9699,
"lon": 77.7004
}
}
}
我的logstash.conf文件内容是：

use_column_value => true
tracking_column => system_timestamp
add_field => {"type" => "vehicle"}
}
}
filter {
if [latitude] and [longitude] {
mutate {
add_field => {
"[location][lat]" => "%{latitude}"
"[location][lon]" => "%{longitude}"
}
}
mutate {
convert => {
"[location][lat]" => "float"
"[location][lon]" => "float"

}
}
}
output {

我尝试了互联网上几乎所有可用的东西。关于如何实现它的任何想法都会有所帮助。提前致谢。:)
