Attach knowledge bases
Attach knowledge bases to give your assistant RAG — retrieval-augmented answers grounded in your documents with citations.
When to attach
Section titled “When to attach”| Scenario | Action |
|---|---|
| FAQ / policy bot | One KB with uploaded docs or crawled help site |
| Product + support | Multiple KBs — see Multi-KB strategy |
| Tools-only bot | Leave KBs detached; tools supply live data |
Attach in the dashboard
Section titled “Attach in the dashboard”- Open app.chatevo.ai → Assistants → select your assistant.
- Go to Knowledge bases.
- Toggle Enable RAG.
- Select one or more knowledge bases from your organization.
- Save and open the test panel to verify citations.
Plan limits
Section titled “Plan limits”| Plan | Max KBs attachable | Documents per KB |
|---|---|---|
| Free | 1 KB | 5 |
| Starter | 1 KB | 20 |
| Standard | 3 KBs | 100 each |
| Pro | 15 KBs | 500 each |
If a KB is greyed out, you may need to upgrade or create the KB first. See Create a knowledge base and Plans compared.
How retrieval works at runtime
Section titled “How retrieval works at runtime”- Query Strategist decides RAG is needed.
- Hybrid search runs across attached KBs in Qdrant.
- Chunks above the similarity threshold pass to the model.
- Reply includes citation metadata for matched sources.
Document classification (public, internal, confidential, restricted) filters which chunks are eligible. See Document classification.
Tuning results
Section titled “Tuning results”Too many irrelevant hits — raise similarity threshold or reduce max results in RAG settings.
Missing answers — lower threshold, add documents, or enable smart query understanding (Starter+) for better query rewrite.
