Question

我正在使用 elasticsearch java Api，我正在尝试运行此查询来检索结果。但我遇到了一个解析异常。 你能帮我弄清楚问题出在哪里吗？ 我将不胜感激

                    }
                }
            }
        }
    }
}

这是我得到的例外

Answer 1

execution_hint 参数不接受 global_ordinals_low_cardinality 值，而只接受 map 和 global_ordinals。

您需要确保您的客户端 Java API 的版本与您的 ES 集群的版本同步，因为您似乎使用的是旧的客户端 Java API。
