Jerry Liu分享了做生产级Agent检索的踩坑经验，分块、同步、重排序这些细节怎么调全告诉你，不是新理论。
Jerry Liu（LlamaIndex创始人）强调2026年构建高质量检索系统的重要性，外部模型能力虽提升，但生产中的Agent检索仍需投入工程时间调优分块、同步、重排序、工具API设计、权限等细节。具体技巧包括：将内容追加到Slack线程作为连续块并利用启发式确定上下文、实现Slack实时更新、为代码库独立分块/更新、混合搜索效果良好、以及为不同项目设置自然的数据源防护栏。这些经验来自LlamaIndex内部Index功能的生产化过程。

I'm glad people still understand the importance of building high-quality retrieval systems in 2026, especially as the outer models/harnesses are getting better every day. Making agentic retrieval work in production doesn't necessarily require groundbreaking new techniques around retrieval or planning. This article shows that you do need to spend engineering time tuning chunking, synchronization, reranking, tool API design, permissioning, and more. Some interesting tidbits: * Concatenating onto existing Slack threads as one contiguous chunk with heuristics for determining additional relevant context * Real-time updates for Slack * Separate chunking/updates for codebases * The discovery that hybrid search works well (not like this was a super new realization, but always good to validate and understand the specific parameters they tweaked) * Having natural guardrails on which data sources are relevant for which projects Building simple retrieval is easy, building production retrieval is hard. We had to deal with a lot of these challenges when productionizing our own Index feature within LlamaParse. Cerebras @cerebras x.com/i/article/2077… 🔗 View Quoted Tweet 💬 3 🔄 1 ❤️ 12 👀 1822 📊 6 ⚡
