LlamaIndex Development in Wrexham
Building retrieval systems on LlamaIndex for Wrexham 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

LlamaIndex Development in Wrexham — 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 Document type, date, department and status let a query about current policy exclude superseded versions entirely, which solves a class of wrong answer that no amount of better semantic matching will fix.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 Source documents change, and an index built once will confidently answer from a version that was superseded months ago — with no signal to the user that it has done so.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 Wrexham?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Wales, including Wrexham and the surrounding Wrexham area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Wrexham businesses do you usually work with?
- Manufacturing and food production systems for businesses on the border serving North West England customers. Beyond that we work across Manufacturing, Food Production, Logistics, Higher Education and Retail.
- Do you cover the areas around Wrexham?
- Yes — we work throughout Wales, including Chester, Liverpool, Bangor. Wrexham is an urban area of roughly 65,000+, and we take on work across the wider Wrexham region rather than the city boundary alone.
