Elasticsearch shows float types as string in output

[Ata_Zangene]

I have a sample schema like this

"coordinate": {
    "properties": {
			  "geo": {
        "type": "geo_point"
      },
      "latitude": {
        "type": "float"
      },
      "longitude": {
        "type": "float"
      }
    }
  }

when I search in index, I got this result

 "coordinate": {
      "geo": {
          "lat": "55.86167039999999",
          "lon": "-4.2583345"
      },
      "latitude": "55.86167039999999",
      "longitude": "-4.2583345"
  }

however I expect the result in the search be float, not string type ( you can see the latitude , longitude result is string )

also when in rust, I use this type:

pub geo: Option<GeoPoint<DefaultGeoPointMapping>>,

I got the error that the geo expect an array with two numbers

where am I doing wrong?

Hi @Ata_Zangene

The "_source" will always reflect the source document as it arrived for indexing, even if the fields are correct...

Fields are "indexed" and searched and aggregated against... the _source is the source data.

Take a look at this and see if it helps
