LlamaIndex 给 LlamaParse 加了 Retrieval Harness，让 agent 能同时用语义搜索和 grep，处理百万级文档。想构建高级 RAG 的可以试试。
LlamaIndex 在 LlamaParse 中上线 Retrieval Harness，提供面向 agent 的检索工具集。它支持混合检索（向量搜索与关键词搜索结合，可调 alpha 值）、文件列表（可扩展的 ls 操作）、文件内正则搜索（File Grep）以及文件子段读取（File Read）。该功能已在所有付费 tier 的 beta 版本中可用，可处理从 10 份到 100 万份以上的文档集合。

We're excited to introduce the Retrieval Harness in LlamaParse - which is the 2026 version of RAG over documents Generalized agents need the right set of tools to scalably search and read through an arbitrary corpus of data (from 10 docs to 1m+ docs). They can already demonstrate great retrieval performance over a local filesystem, need a proper backend for a large collection of managed data. The Retrieval Harness exposes a diverse set of tools for various needs: 1. Hybrid Retrieval: Combine vector search with keyword search, let the agent set the alpha value to toggle between the two 2. List Files: a scalable version of `ls` to list files within an index 3. File Grep: enable regex search within a given file 4. File Read: Allow agents to read a subsection from an existing document. The agent can choose to interleave any sequence of these tools in order to complete a variety of tasks, from simple to hard. Come check it out!

Neither does brute-force grep. Agents need both. Today we're shipping the Retrieval Harness in LlamaParse Index: semantic search, server-side grep, and file-level navigation working together in a single agent reasoning loop. 🦙🌤️ Grep a file, list what's in an index, read past a chunk boundary, run hybrid search with reranking — all as native agent tools.
