Grounded Retrieval

Enterprise Knowledge Retrieval — every answer grounded in your own documents.

We turn scattered documents, wikis, contracts, and tickets into a single answer engine. Every response cites its sources, and every query respects who is allowed to see what.

What's included

A complete answer engine, not just a vector index.

Ingestion, ranking, citations, and access control — the full layer that makes retrieval trustworthy at work.

Hybrid search & re-ranking

Semantic plus keyword retrieval, tuned on your actual content and real queries — not a generic benchmark.

02

Grounded answers with citations

Every response links to the source passages it was built from, down to the page.

03

Role-based access control

Users only ever get answers from documents they're permitted to see, checked per query.

04

Retrieval quality benchmarks

A graded test set from real questions, so accuracy is measured and improves over time.

05

Admin & analytics console

See what people ask, where answers fail, and which knowledge gaps to fill.

Case study

Internal Policy Assistant, Fully Cited

Financial services · Regional bank

The challenge

Hundreds of internal policy questions a month, answered from memory by two senior staff who'd become an unofficial bottleneck for the entire compliance team.

The approach

We ingested the policy library and past clarifications into a permission-aware RAG system with citations on every answer, and a hard rule: if sources don't support an answer, say so and route to a human.

Policy question → hybrid retrieval → grounded generation → citation check → cited answer or escalation
91%Answered without escalation
100%Answers carry a citation

Typical approach
With elhaa
Answers
From the model's memory — plausible, unverifiable
Grounded in your documents, with citations

How the engagement runs

Four steps from audit to a maintained system.

1

Corpus audit

Map the document sources, formats, permissions, and the questions people actually ask.

2

Prototype

A working retrieval system on a representative slice of your content.

3

Tune & benchmark

Iterate on chunking, ranking, and prompting against a real question set.

4

Deploy & maintain

Production rollout with access control, monitoring, and index freshness jobs.

How success is measured

Agreed in week one, on a dashboard by go-live.

Retrieval

Precision & recall

Does the system find the right passages for real questions?

Trust

Groundedness

Share of answer claims actually supported by the cited sources.

Honesty

Correct refusals

How often “I don't know” is said exactly when it should be.

Adoption

Helpfulness ratings

Thumbs-up rate and repeat usage from real users.

FAQ

Questions about Enterprise Knowledge Retrieval.

Yes — OCR and layout-aware parsing are part of the ingestion pipeline. Quality varies by scan, so the corpus audit flags problem documents early.

RAG dramatically reduces fabrication because answers must be grounded in retrieved passages, and we configure the system to decline when sources are insufficient. Our benchmarks measure exactly this.

Wherever your security policy requires — your cloud tenant, your VPC, or on-premises. Document content stays inside your boundary.

Configurable per source — from near-real-time for critical repositories to daily sync for archives. The admin console shows index freshness so you always know what the system has seen.

Yes. Modern embedding and generation models handle major languages well, including mixed-language corpora — a document ingested in one language can be asked about in another. We include your actual language mix in the benchmark set to verify quality rather than assume it.
