LlamaIndex Development in Southampton

Building retrieval systems on LlamaIndex for Southampton 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 Southampton — 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 Document type, date, department and status let a query about current policy exclude superseded versions entirely, which solves a class of wrong answer that no amount of better semantic matching will fix.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 Source documents change, and an index built once will confidently answer from a version that was superseded months ago — with no signal to the user that it has done so.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 Hampshire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout South East, including Southampton and the surrounding Hampshire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Southampton businesses do you usually work with?
Scheduling and capacity systems that survive seasonal peaks are the recurring need, driven by the port, cruise and tourism economy. Beyond that we work across Maritime & Shipping, Cruise & Tourism, Higher Education, Healthcare and Logistics.
Do you cover the areas around Southampton?
Yes — we work throughout South East, including Portsmouth, Reading, Bristol. Southampton is an urban area of roughly 330,000+, and we take on work across the wider Hampshire region rather than the city boundary alone.
