地理空间查找返回错误的结果

如何解决地理空间查找返回错误的结果

我在识别一个点是否在多边形内时遇到问题。

对于相同的纬度和经度，有时我会得到正确的结果，但有时不会。如果我搜索更多 ID（因此有更多事件）或更改时间范围（不一定更大），我会得到错误的结果。

导致问题的行：|查找 some_lookup_name 纬度经度

我已使用示例数据和简单的地理空间查找重现了该问题。 id=1 的所有事件都在地理围栏内，id=2 的事件在外。我得到的结果不正确（根据时间排序时不同）。我有两个示例数据源（data_sample_2 已将 id=2 的事件之一的纬度从 51.501835 更改为 51.501836）。

When sorting from earliest to latest,all events are inside

When sorting from latest to earliest,some events for id=1 are outside (which is incorrect)

Removing event with problematic latitude

搜索：

index="debug_idx" source="data_sample_1"
| eval time_epoch=_time
| sort 0 _time
| lookup geo_4 latitude longitude
| table id latitude longitude _time time_epoch featureId featureCollection
| noop search_optimization=false

Data_sample_1：

{"location":{"state":{"position":{"timestamp":"2021-01-11T01:14:34.000Z","latitude":51.501835,"longitude":6.906453}}},"ident":{"attr":{"id":"2"}}}}
{"location":{"state":{"position":{"timestamp":"2021-01-11T01:14:34.000Z","ident":{"attr":{"id":"2"}}}}
{"location":{"state":{"position":{"timestamp":"2021-01-06T22:23:23.000Z","latitude":53.500091,"longitude":9.909387}}},"ident":{"attr":{"id":"1"}}}}
{"location":{"state":{"position":{"timestamp":"2021-01-06T22:16:58.000Z","latitude":53.49732,"longitude":9.9082}}},"ident":{"attr":{"id":"1"}}}}
{"location":{"state":{"position":{"timestamp":"2021-01-06T22:13:30.000Z","latitude":53.501923,"longitude":9.910017}}},"ident":{"attr":{"id":"1"}}}}
{"location":{"state":{"position":{"timestamp":"2021-01-06T22:13:15.000Z","ident":{"attr":{"id":"1"}}}}

Data_sample_2：

{"location":{"state":{"position":{"timestamp":"2021-01-11T01:14:34.000Z","latitude":51.501836,"ident":{"attr":{"id":"1"}}}}
