LlamaIndex Development in Oxford
Building retrieval systems on LlamaIndex for Oxford organisations, where the index is the product. A capable model given the wrong three paragraphs will answer confidently and wrongly, so how documents are split, enriched and ranked determines quality far more than which model sits at the end of the pipeline.
Why this comes up
The problem
The system retrieves passages that mention the right words and miss the passage that actually answers the question.
What you get
What we deliver
- Chunking designed around document structure rather than a fixed character count
- Metadata attached at ingestion so retrieval can filter as well as match
- Hybrid retrieval where keyword and semantic search each cover the other's gaps
- Reranking applied when the first pass returns plausible but unhelpful passages
- Source attribution returned, so answers can be checked against the document
- Ingestion built to re-run, because documents change and indexes go stale

Working in Oxford
South East
Oxford's economy runs on research and life sciences, and a lot of the work here starts with a research group or spin-out that needs a prototype turned into something other people can safely use.
Research groups and spin-outs needing a prototype turned into a supportable product make up most of the local demand.

LlamaIndex Development in Oxford — common questions
- Why does chunking matter so much?
- Because it decides what can be retrieved together. Splitting on a character count cuts tables in half and separates a heading from the paragraph it governs, so the retrieved fragment lacks the context that made it meaningful in the document.
- What does metadata add?
- The ability to narrow before matching. Document type, date, department and status let a query about current policy exclude superseded versions entirely, which solves a class of wrong answer that no amount of better semantic matching will fix.
- Is semantic search enough on its own?
- Usually not. It handles paraphrasing well and struggles with exact terms — product codes, names, specific clauses — where keyword matching is precise. Running both and combining the results covers considerably more question types than either alone.
- How do we keep the index current?
- Treat ingestion as a pipeline that runs, not a task that was done. Source documents change, and an index built once will confidently answer from a version that was superseded months ago — with no signal to the user that it has done so.
- Do you work with businesses across Oxfordshire?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Oxford and the surrounding Oxfordshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Oxford businesses do you usually work with?
- Research groups and spin-outs needing a prototype turned into a supportable product make up most of the local demand. Beyond that we work across Research & Higher Education, Life Sciences, Publishing, Technology and Tourism.
- Do you cover the areas around Oxford?
- Yes — we work throughout South East, including Reading, Milton Keynes, Cambridge, London. Oxford is an urban area of roughly 170,000+, and we take on work across the wider Oxfordshire region rather than the city boundary alone.
