AI Smart Search ✨ – Listeo Knowledge Base

AI Search feature in PurioChat is dedicated for Listeo and brings natural language search to your directory website with OpenAI or Gemini or Mistral AI. Users can search using everyday phrases instead of just keywords.

Try it yourself on our demo: https://listeo.pro/

Key Benefits:
✅ Natural Language: Users can search like they talk: cozy restaurant with outdoor seating.
✅ AI understands context and finds businesses that meet user needs.
✅ Analytics Insights: Track popular searches to understand your users better.

What Users Search For	Standard WordPress Search	Listeo AI Search
romantic dinner spot	❌ No — “romantic” rarely appears in restaurant listings	✅ Finds fine dining, intimate cafes, date-night restaurants
dog grooming services Pet care needs	⚠️ Maybe — only if exact words “dog grooming” appear	✅ Finds pet salons, mobile groomers, veterinary services
kids birthday party venue	❌ No — exact phrase not in venue descriptions	✅ Shows party halls, entertainment centers, kid-friendly venues

The plugin creates a vector database by turning each listing into an embedding — a unique numerical representation capturing its meaning. User queries get converted the same way, then matched mathematically to find the closest results.

Plugin is automatically installed with Listeo. However, if you can’t see it or have an older theme version, you can download it manually:

FAQ

I see not enough or no search results at all
Follow this checklist:
1. ✅ Make sure your listings have AI embeddings generated.
2. ✅ Make sure your listings have keyword-rich descriptions.
3. ✅ Try the Query Expansion feature.
4. ✅ Lower the Minimum Match Percentage setting.
5. ✅ Clear cache in PurioChat → Developer & Debug Options → Clear Cache. Cached search results may prevent new results from appearing immediately.
Why are search results decent but not perfect?

AI search understands meaning, so it finds relevant results even when the exact words aren’t in your listings. That’s why it can match “romantic dinner spot” with fine dining restaurants or “dog grooming” with pet salons.

But it’s not magic — it works from the text in your listings. If a listing has almost no description, or uses very unusual wording, the AI may miss it. Also, in rare cases, it might return a result that feels related but isn’t exactly what the user meant.

In short: it’s far better than keyword search, but like any search, it depends on good, descriptive content.
What does 'Minimum Match Percentage' control?
This setting determines how closely a listing must match the search query to appear in results.

Setting range: 0–100
Default: 65

Impact on search results:
- Lower values, 40–60: More results, but some may be less relevant.
- Medium values, 65–75: Balanced relevance and quantity. Recommended.
- Higher values, 80–95: Fewer but highly relevant results.
Example:
- Query: Italian restaurant
- 50% threshold: returns pizza places, pasta shops, Mediterranean food.
- 80% threshold: only returns specifically Italian restaurants.
Should I enable 'Query Expansion'?
Query expansion uses AI to understand and broaden search terms for better results.

Example:
- Original query: coffee shop
- Expanded query might include: café, espresso bar, coffee house
Trade-offs:
- ✅ Enabled: better coverage and more results, but not always perfectly relevant. This depends on the minimum match settings.
- ❌ Disabled: faster processing and more literal searches.
What data is processed by OpenAI/Gemini/Mistral in AI Search?
After installing the plugin, adding your OpenAI, Gemini, or Mistral API key, and clicking Start Training, the plugin sends structured listing data to the selected embeddings model to create vector embeddings.

Processed listing data may include:
- Listing name
- Category
- Location
- Amenities and features
- Description
- FAQ
- Pricing or menu data
- User reviews, positive only, rating ≥ 3.0
When this happens:
- Manual regeneration via the admin panel
- Daily cron job: listeo_ai_update_embeddings for changed listings
- When a listing is created or updated, if auto-update is enabled
What happens when a user searches?
- Listings data is not sent again when the user searches.
- The user’s search query text is sent to the selected AI provider to generate an embedding vector.
- This vector is compared locally against stored embeddings. No additional listing data is sent during the search.
