度量方式，可选值为：euclidean、inner_product、cosine、hamming。 默认值：euclidean。 Painless语法扩展查询 CSS扩展实现了多种向量距离计算函数，可在自定义的painless脚本中直接使用，用以构建灵活的重打分公式。 示例如下： POST my_index/_search
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
OpenSearch提供了标准的REST接口，以及Java、Python等语言编写的客户端。 本节提供一份创建向量索引、导入向量数据和查询向量数据的Python代码示例，介绍如何使用客户端实现向量检索。 前提条件 客户端已经安装python依赖包。如果未安装可以执行如下命令安装： pip install opensearch-py==1
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
objects 集群标签。 availability_zone 是 String 可用区。需要指定可用区的名称（可用分区名称）。 默认指定单AZ。指定多AZ时，各个可用分区名称需要使用英文逗号（,）分隔，以“华北-北京四”为例，选择三AZ时，availability_zone取值为cn-north-4a
public static void main(String[] args) { // The AK and SK used for authentication are hard-coded or stored in plaintext, which has great
