HayStackKnowledge

HayStack RAG Knowledge Base implementation.

This class provides integration with HayStack Knowledge Base service, implementing the Knowledge interface to enable seamless RAG (Retrieval-Augmented Generation) capabilities with HayStack-hosted knowledge bases.

Key features:

• Built on HayStack RAG with end-to-end retrieval, ranking, and generation pipelines

• Local or remote HayStack deployment support

• Compatible with Bailian and Dify RAG plugins (same Knowledge interface)

Functional Scope: This plugin focuses on retrieval capabilities only, similar to Bailian and Dify RAG plugins. Document management (upload/delete/update) should be performed via HayStack RAG server.

Example usage:

`HayStackConfig config = HayStackConfig.builder()
.baseUrl("http://localhost:8080")
.topK(10)
.build();

HayStackKnowledge knowledge = HayStackKnowledge.builder()
.config(config)
.build();

// Retrieve documents
List<Document> docs = knowledge.retrieve("What is AI?", retrieveConfig).block();

// Use with Agent
ReActAgent agent = ReActAgent.builder()
.knowledge(knowledge)
.ragMode(RAGMode.AGENTIC)
.build();
`

Note: Document management is not supported via this plugin. Please use HayStack server to upload, delete, and manage documents. This design ensures compatibility with Bailian and Dify RAG plugins and keeps the plugin focused.
