Haystack Development in Reading
Building search and retrieval systems on Haystack for Reading organisations, where the pipeline is declared rather than implied. Components are wired into an explicit graph you can inspect, swap and measure a piece at a time — which matters because retrieval quality problems are almost always located in one component, and finding out which one is most of the work.
Why this comes up
The problem
Answer quality is poor and there is no way to tell whether the retriever, the ranker or the prompt is responsible.
What you get
What we deliver
- Pipelines defined explicitly, with each component measurable in isolation
- Retrieval and generation evaluated separately, since they fail differently
- Classic keyword search used alongside embeddings where precision matters
- Rankers applied and their contribution actually measured, not assumed
- Document preprocessing tuned to the formats you genuinely hold
- Pipelines versioned, so a quality change can be traced to a specific alteration

Working in Reading
South East
Reading anchors the Thames Valley technology corridor, and local firms are often part of large enterprise supply chains where security review and integration standards are set by someone else.
Work here usually has to satisfy someone else's security and integration standards, because clients sit inside larger enterprise supply chains.

Haystack Development in Reading — common questions
- Why evaluate components separately?
- Because an end-to-end score tells you the system is worse without telling you where. If the retriever never returned the relevant passage, no prompt change will help — and teams routinely spend weeks on prompts when the answer was never in the context.
- Is keyword search still useful?
- For exact terms, very. Part numbers, case references, names and codes are matched precisely by keyword search and approximately by embeddings, so systems handling that kind of query benefit from running both rather than choosing.
- Do rankers earn their cost?
- Frequently, and it should be measured rather than assumed. Reranking adds latency and expense, and whether it improves your results depends on your corpus and query patterns — which is exactly the sort of thing a component-level evaluation answers.
- How much does preprocessing matter?
- More than most of the pipeline. Text extracted badly from a PDF, tables flattened into unreadable rows and headers lost from their sections limit everything downstream, and no amount of retrieval sophistication recovers information the ingestion discarded.
- Do you work with businesses across Berkshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Reading and the surrounding Berkshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Reading businesses do you usually work with?
- Work here usually has to satisfy someone else's security and integration standards, because clients sit inside larger enterprise supply chains. Beyond that we work across Technology, Telecommunications, Financial Services and Professional Services.
- Do you cover the areas around Reading?
- Yes — we work throughout South East, including Oxford, London, Milton Keynes, Southampton. Reading is an urban area of roughly 340,000+, and we take on work across the wider Berkshire region rather than the city boundary alone.
