Elasticsearch中GeoShape查詢與WKT/geojson之間的區別-有解無憂

我想知道如果我在 opensearch 中以 geojson 格式存盤空間資料。并使用地理形狀查詢而不是為查詢提供geojson格式來查詢它我以WKT格式提供形狀，它會對查詢產生任何影響嗎？就像它會按預期作業還是會回傳錯誤的結果。

我已經使用一些示例資料進行了嘗試，它按預期作業，但仍希望確保它能夠完美作業或可能導致一些問題。

這是代碼：

  "mappings": {
    "properties": {
      "geometry": {
        "type": "geo_shape",

    }
  }
}

以上這兩個查詢都回傳了相同的結果。
