Use PageIndex to compare reasoning-based retrieval against vector chunking for contracts, policies, and technical manuals.
Skip if you need mature managed enterprise search connectors first.
Traditional RAG can retrieve text that is semantically similar but not actually relevant to the user's question. Long financial reports, contracts, and technical documents often require section-aware reasoning, source traceability, and context beyond isolated chunks.
PageIndex uses document structure and LLM reasoning instead of requiring vector databases and chunk similarity as the primary retrieval layer.
The README describes a table-of-contents tree structure that lets an LLM search sections in a way closer to how a human expert navigates a long document.
PageIndex emphasizes explainability and section references, helping users verify where an answer came from before acting on it.
PageIndex is better when long-document answers need reasoning over document structure and traceable section references. Vector databases are still better when teams need mature high-scale embedding search, broad integrations, and predictable nearest-neighbor retrieval over many short chunks.
PageIndex is a vectorless, reasoning-based RAG framework for retrieving answers from long documents.
No. The README positions PageIndex around document structure and reasoning rather than vector database retrieval.
PageIndex is best for long professional documents where source traceability, section context, and reasoning matter.
