v1.6 — Semantic Search

Released 2025-08-19.

Added

• Semantic search — every uploaded document is embedded; queries are embedded and matched
• Hybrid ranking — combines SQL Server full-text score with semantic similarity
• Q&A endpoint at /api/v1/search/qa — retrieval-augmented question answering against the tenant's corpus
• Related documents panel on document detail view — top-3 semantically similar documents

Changed

• Search bar UI — now shows result type (Document / FAQ / Person / Contract) inline
• Search results — display semantic confidence score for transparency

Performance

• Embedding generation moved to background queue; document upload no longer blocks on embedding
• Vector store is Qdrant Cloud (per-tenant collections); average query latency under 80ms

Fixed

• Cross-language semantic search (English query → Swahili document) was producing biased results favouring English; now corrected with multilingual embedding model
