召回引擎版支持RAG方案_智能开放搜索 OpenSearch(Open Search)-阿里云帮助中心

本文介绍如何使用OpenSearch智能问答版为OpenSearch召回引擎版提供RAG能力。

假设用户已经购买了召回引擎版实例，则只需购买智能问答版实例，这两个实例的具体作用如下：

召回引擎版实例负责：

存储用户文档数据，向量数据
召回用户文档数据，向量数据

智能问答版实例负责：

对用户文档进行切片和向量化（非必须）
对用户原始query进行向量化（非必须）
对召回结果进行推理和总结

具体操作流程如下图所示：

1. 创建和配置实例

1.1. 创建和配置召回引擎版实例

1.1.1. 购买OpenSearch召回引擎版实例

如果用户已经有了召回引擎版实例，则无需再购买新实例。

购买新实例可参考购买OpenSearch召回引擎版实例。

1.1.2. 配置OpenSearch召回引擎版实例

如果用户不想修改现有召回引擎版实例的查询和召回逻辑，则无需对现有实例配置进行修改，只需调用智能问答版的问答接口，对现有召回结果进行推理和总结即可（直接参见3.3章节）。

如果用户想要对现有实例中的数据内容做切片向量化，则需要修改已有配置。

在实例列表页，点击配置，进入实例配置流程，如下图所示：

1.1.2.1. 数据源配置

点击添加数据源，选择api数据源

配置说明：

数据源名称：可自定义

点击确定后，数据源会保存至列表页，点击下一步，进入索引结构配置页面。

1.1.2.2. 索引结构配置

为了保存用户切片数据、向量数据，用户表结构中必须包含以下字段：

文档主键，如下图中的doc_id；
文档切片后内容字段,如下图中的split_content；
文档切分后内容向量化值，如下图中的split_content_embedding。该字段需要设置为向量字段，并以","分割。

除上述必须字段外，客户可以自定义添加其他业务字段，并使用这些字段做查询，排序，过滤等，来满足客户的业务需求。如下图所示：

索引配置说明：

主键id需要配置主键索引：PRIMARYKEY64
content和split_content需要配置PACK索引或者TEXT索引
split_content_embedding需要配置向量索引，向量索引维度为1536维，其他参数默认即可

索引配置，如下图所示：

配置完成之后，点击确认发布，生成表结构和相关索引字段

点击下一步，进行索引重建

1.1.2.3. 索引重建

数据源选择api数据源，时间选择当前时间，如下图所示

点击下一步，配置完毕

可在变更历史中查看索引重建进度，进度完成后，说明表已经就绪，可以进行后续流程。

1.2. 创建和配置智能问答版实例

1.2.1. 购买和配置OpenSearch智能问答版实例

购买实例可参考快速入门。

智能问答版实例无需特殊配置，实例购买完成即可使用。

2. 数据入库：

2.1. 对文档内容进行切片和向量化

在用户原始文档内容比较大的情况下，无法直接用原始文档直接调用智能问答版对话接口进行推理总结。

这就需要调用智能问答版实例相关endpoint和api，对用户原始文档内容进行切片和向量化。

请参考本文末尾的JAVA SDK Demo，或者参考文章：

SplitDoc-文本切片及向量化

2.2. 将切片和向量化之后的文档推送到召回引擎版实例

在2.1返回结果中：

chunk_id为切分后的文档id。需要和原始文档id拼接起来，组成新的文档主键：doc_id
chunk为切分后文档内容，对应split_content;
embedding为切分后文档内容向量化值,对应split_content_embedding;

需要将上述结果推送到召回引擎版实例。

调用召回引擎版实例相关endpoint和api，请参考本文末尾的JAVA SDK Demo，或者参考文章：

数据推送 Demo

3. 查询问答：

3.1. query向量化

将用户原始查询内容进行向量化。

调用智能问答版实例相关endpoint和api，请参考本文末尾的JAVA SDK Demo，或者参考文章：

EmbeddingDoc-文本向量化

3.2. 召回向量化结果数据

使用query的向量化的结果，去召回引擎版进行召回
处理query的向量化召回外，用户可以使用其他表字段进行召回，还可以对召回结果进行排序，过滤等

调用召回引擎版实例相关endpoint和api，请参考本文末尾的JAVA SDK Demo，或者参考文章：

文档搜索 Demo

3.3. 大模型推理总结

基于召回引擎版召回的结果，调用智能问答版的大模型问答接口，进行推理总结。

请参考本文末尾的JAVA SDK Demo，或者参考文章：

KnowledgeLLM-大模型对话接口

4. JAVA SDK Demo：

使用Java SDK完成数据推送和智能问答的demo如下：

添加maven依赖：
