Search & Re-Ranking.

Generative AI, scoped to the shape of the problem it solves.

Semantic and hybrid search with LLM-based re-ranking for retrieval-quality lift.

Use-case context

Search is the single highest-traffic surface in most digital products, and BM25-only stacks leave measurable revenue and engagement on the table once query intent gets richer than keyword match. Bolt-on vector search alone tends to underperform a tuned BM25 baseline once the corpus is messy, so naive replacements often look worse in A/B. We build hybrid retrieval — BM25 plus dense vectors plus a learned re-ranker — tuned against your actual click and conversion logs, with relevance evaluation baked into the deployment loop. The re-ranker is small, fast, and observable, not a frontier-LLM call on every query. Measured by NDCG@k and MRR against a labelled relevance set, plus click-through rate and downstream conversion or task-success lift in live A/B against the existing search stack. Latency and per-query cost are tracked as hard ceilings. We do not roll out search-ranking changes without an A/B test or interleaving test against the incumbent ranker — relevance changes that look better offline frequently lose in live traffic. In our coverage footprint this lands first across legal, technology, retail — the sectors where the data shapes and evaluation criteria line up cleanly with what this use-case actually measures.

Why work with Veso AI on search & re-ranking

Measured

Evaluation, not opinion

Measured by NDCG@k and MRR against a labelled relevance set, plus click-through rate and downstream conversion or task-success lift in live A/B against the existing search stack. Latency and per-query cost are tracked as hard ceilings.

Fixed-fee

After paid discovery

Two-week discovery assembles the labelled evaluation set with your subject-matter experts, then converts into a fixed-fee proposal with explicit gates.

Your repo

Your IP, day one

Code, infrastructure-as-code, evaluation harness, and runbooks land in your accounts — no vendor lock-in on the data, models, or evaluation history.

FAQ

Search & Re-Ranking — frequently asked questions

How is success measured for search & re-ranking engagements?

Measured by NDCG@k and MRR against a labelled relevance set, plus click-through rate and downstream conversion or task-success lift in live A/B against the existing search stack. Latency and per-query cost are tracked as hard ceilings. The evaluation harness is part of the deliverable, not an afterthought — we build it during the engagement so your team can run it against the next prompt, model, or pipeline change without us.

Where does Veso AI NOT apply search & re-ranking?

We do not roll out search-ranking changes without an A/B test or interleaving test against the incumbent ranker — relevance changes that look better offline frequently lose in live traffic. This is a deliberate trust boundary, not a capability gap — we are equipped to build the systems we decline to build, and we decline to build them because the risk-to-value ratio in those surfaces does not justify it.

Which industries does search & re-ranking apply to?

In our coverage footprint, search & re-ranking most commonly lands in legal, technology, retail, media. The specific deployment shape varies by industry — data shapes, evaluation criteria, and regulators differ enough that we re-scope each engagement against the sector it lands in.

What data shape do you need to start a search & re-ranking engagement?

Product / document / case catalogues, query logs, click logs, conversion or task-success signals, and a relevance-judgement set assembled with your subject-matter experts. During the paid two-week discovery we map the actual data surface — what exists, what is labelled, what residency posture it carries — and the proposal for the next gate is shaped against that, not against an assumption.

Which Veso AI services ship search & re-ranking?

search & re-ranking ships under our Generative AI Consulting, Custom Software Development, AI Integration Services, Data Science & Analytics service lines, depending on the integration surface and the build-vs-platform trade-off. Most engagements draw on more than one — the boundary between consulting, custom build, and integration is a scoping decision we make explicit during discovery.

How does a search & re-ranking engagement typically start?

With a paid two-week discovery: workshops with leadership and operators, an evaluation-set assembled with your subject-matter experts, and a fixed-fee proposal for the next gate. The evaluation set anchors every subsequent decision — model choice, prompt strategy, retrieval design — so quality is measurable from week one, not from go-live.
