Question 1

What is CBRS: Corporate Knowledge RAG System with Document Ingestion and Semantic Search?

Accepted Answer

Question 2

What problem does CBRS: Corporate Knowledge RAG System with Document Ingestion and Semantic Search solve?

Accepted Answer

Organizations accumulate large volumes of internal documents — policies, procedures, technical manuals, compliance documents, HR handbooks — that employees reference regularly.

Discovery is poor: employees don't know which document contains which information. Shared-drive search returns filenames, not answers. Outdated documents cause policy violations when staff can't find the current version.…

Question 3

Why was CBRS: Corporate Knowledge RAG System with Document Ingestion and Semantic Search built?

Accepted Answer

Corporate knowledge lives in dozens of PDFs and Word files that nobody reads end-to-end. HR and compliance teams field the same policy questions repeatedly because search only returns document links.

I built CBRS with strict module separation — ingestion never calls the LLM, embeddings are swappable, vectors are swappable — so each layer could be tested and replaced independently as the corpus a…
