AI-powered search
Synonyms: semantic search, neural search, intelligent search, conversational search, vector search UX
Definition
Use cases
- Handling vague queries: A user types “warm jacket” into an e-commerce app. Semantic search can prioritize winter coats over unrelated products that simply contain the words “warm” or “jacket.”
- Recovering from typos: AI-powered search can interpret misspellings and intent together, reducing the need for exact spelling or repeated searches.
How it's used in practice
- Study how users naturally phrase queries before configuring the search experience
- Build fallback states for failed searches: suggested categories, related products, or guided filters
- Track zero-result queries and low-click searches to identify search quality issues
- Test using messy real-world queries from support tickets, search logs, and autocomplete history
- Add lightweight clarification patterns like “Did you mean…?” suggestions when confidence is low
Challenges & limitations
- Limited explainability: It can be difficult to understand why certain results ranked above others, especially during debugging or usability testing.
- Latency pressure: Users expect search to feel nearly instant. Even strong results feel broken when response times are too slow.
