SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Build production-grade RAG systems with semantic chunking, incremental indexing, and filtered retrieval for scalable document ingestion and context-aware retrieval.

Core Features & Use Cases

  • Semantic chunking using semantic boundaries (## headers) with a target ~400 tokens and 15% overlap to preserve context.
  • Incremental indexing and change detection via file hashes to minimize reprocessing and keep indices fresh.
  • Payload-indexed Qdrant-backed vector search enabling context expansion and precise filtering across modules, chapters, and performance levels.
  • End-to-end ingestion pipeline from crawling to vector upsert, suitable for production workflows in large corpora.

Quick Start

Install the required dependencies and start the ingestion workflow to build a production-grade RAG system.

Frequently Asked Questions about building-rag-systems

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a RAG system with semantic chunking for large document corpora?▼

Build a RAG system by applying semantic chunking using document headers to create ~400 token segments with 15% overlap, preserving context across large corpora during retrieval. Use incremental indexing via file hashes to update vectors only when content changes.

How does incremental indexing work with Qdrant vector search?▼

Incremental indexing detects document changes via file hashes to minimize reprocessing, then upserts updated vectors into Qdrant with payload indexing, enabling efficient filtered retrieval and context expansion without rebuilding the entire index.

What's the best way to set up an ingestion pipeline for production RAG?▼

Set up a production RAG ingestion pipeline by crawling source documents, applying semantic chunking strategies, computing file hashes for change detection, and performing vector upserts into Qdrant with payload indexes for module and chapter filtering.

Can I filter vector search results by document structure in Qdrant?▼

Filter vector search results in Qdrant using payload indexing to restrict retrieval by metadata fields like modules, chapters, or performance levels, enabling precise context-aware retrieval across large document collections.

Why use semantic chunking instead of fixed-size chunking for RAG ingestion?▼

Semantic chunking splits documents at natural header boundaries rather than arbitrary character counts, producing coherent ~400 token segments with 15% overlap that maintain context and improve retrieval accuracy across large corpora.

Does this RAG approach support context expansion across multiple document modules?▼

Yes, context expansion is supported through Qdrant payload indexing, allowing filtered retrieval across document modules and chapters to gather surrounding context and deliver more complete answers from large corpora.
