LlamaIndex搞了个Index v2，让你的AI代理能像逛文件系统一样搜索知识库，还能自动更新。legal-kb示例已开源，法律金融场景直接上手。
LlamaIndex推出了Index v2，一个用于现代代理检索的综合工具。它提供持久化数据管道，可连接数据源、索引并更新大型知识库，暴露语义搜索、正则grep、文件搜索和读取等类似文件系统操作的工具。该工具可集成到任何AI代理中，让代理自主爬取知识库解决复杂任务。参考实现legal-kb展示了在法律和金融领域的应用，具备版本控制、可视化引用和数据导出能力。

We've created a comprehensive Retrieval Harness for modern agentic retrieval in 2026. The harness provides a persistent data pipeline that can connect to a data source, index and update a large knowledge base, and expose a broad set of tools akin to filesystem operations (semantic/keyword search, regex grep, file search, read). You can plug this into any of your agents to let them autonomously crawl an arbitrary knowledge base to solve a task with any complexity.

That’s exactly the use case we designed Index v2 for. To demonstrate what’s possible, we built legal-kb, a reference application that integrates Index v2 into an agentic knowledge automation workflow. It uses Index v2 as the underlying knowledge base and exposes its retrieve, read, grep, and find APIs as tools that an AI agent can use to autonomously explore and reason over your documents. With legal-kb, you get: 📚 Project-scoped knowledge bases for agent-powered chat 📖 Visual citations directly in agent responses 🌿 Version control for your knowledge base 📦 Data export capabilities Try it o legal-kb.dev MEGx Explore the co github.com/run-llama/lega… KZdn Get started with LlamaPar cloud.llamaindex.ai/signup 1Brf Your browser does not support the video tag. 🔗 View on Twitter 🔗 View Quoted Tweet 💬 2 🔄 0 ❤️ 4 👀 560 📊 3 ⚡
