Ollama-powered semantic query understanding for better search results

Find relevant knowledge even with imperfect queries

Tasks

• Generate multiple embedding variations
• Query Qdrant with all variations
• Merge and de-duplicate results
• Rank by semantic similarity + recency
• Show "searched for: X, Y, Z" to user
• Cache expanded queries (Redis)

Success Criteria

• know search "redis" finds entries about "cache", "key-value store"
• Relevant results even with typos or informal language
• Query expansion < 500ms (cached) or < 2s (uncached)
• Top 3 results are relevant 80%+ of the time
