Rag Lessons

RAG 知识库质量巡检需要每天抽取少量题目进行自动测试。如果随机抽样，容易连续抽到同一类型的问题（如连续三天都是报警代码题），漏掉其他分类的质量退化。

When HermesHub starts, if the BGE-m3 model has not been downloaded to the local path, SkillIndexer crashes immediately.

Agent 内跑 BGE-large-zh 建库（约30分钟），Gateway 重启后整个数据库为空，0条向量入库。

访问者问"fanuc r-2000ic 系列所有机器人的最大速度"，RAG 返回了 KUKA Series 2000 的数据。

After continuous document imports, the RAG knowledge base developed data contamination, version confusion, inconsistent

When querying "SRVO-023 robot alarm", RAG returned unrelated results instead of the correct FANUC alarm documentation.

一个面向特定品牌的垂直 RAG 知识库（200K+ 向量），在每日巡检中发现部分查询答案混入了竞品品牌技术内容。例如：

During knowledge-base construction (chunks_v3, 34,100 docs), all data was loaded into VRAM/WSL memory at once. This caus

When building a FANUC knowledge-base RAG system, retrieved Chinese alarm codes appeared garbled.

After importing FANUC PDF documents into RAG, retrieval quality was unstable and recall was low for long documents.

RAG knowledge-base queries take 40-60 seconds on CPU-only infrastructure.

RAG 知识库包含完整的 FANUC M-900iB/330L 规格表，但 agent 回答"M-900iB/330L 不存在"。六个独立层级各自丢弃了有效 chunk — 无单一修复足够。

When serving a RAG knowledge base externally (Gradio Web UI / WeChat bot), a single LLM API path may become unavailable
