Search & Re-Ranking.

Generative AI, scoped to the problem it solves.

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

Use-case context

Search is the highest-traffic surface in most digital products, and BM25-only stacks leave measurable revenue and engagement on the table once query intent goes beyond keyword match. Bolt-on vector search alone underperforms a tuned BM25 baseline on a messy corpus, so naive replacements often look worse in A/B. We build hybrid retrieval (BM25, dense vectors, and a learned re-ranker) tuned against your real 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 your existing stack. Latency and per-query cost are hard ceilings. We do not roll out ranking changes without an A/B or interleaving test against the incumbent ranker. Relevance changes that look better offline often 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.

Data shape

Product / document / case catalogues, query logs, click logs, conversion or task-success signals, and a relevance-judgement set assembled with your subject-matter experts.

Where we draw the line

We do not roll out ranking changes without an A/B or interleaving test against the incumbent ranker. Relevance changes that look better offline often lose in live traffic.

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 your existing stack. Latency and per-query cost are hard ceilings.

Proven

Quality you can measure

In the first two weeks we build a labelled evaluation set with your experts, so quality is measured from day one, not hoped for.

Production

Built to operate

We hand over working software, infrastructure-as-code, and an evaluation harness your team can run and maintain.

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 your existing stack. Latency and per-query cost are 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 ranking changes without an A/B or interleaving test against the incumbent ranker. Relevance changes that look better offline often 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. In the first two weeks we look at the real data (what exists, what is labelled, where it has to live) and build the plan around what is actually there, not around 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?

We spend two weeks with your leadership and operators, build an evaluation set with your subject-matter experts, and come back with a clear plan and a clear price. That evaluation set anchors every decision after it (model choice, prompt strategy, retrieval design) so quality is measurable from week one, not from go-live.
