Some changes may require re-indexing documents. Access Settings: 1\. Open the Knowledge Base 2\. Click the Settings tab (or gear icon) ## Change Index Method You can switch between 2 index methods:


Method	Description
High Quality	Uses Embedding Model to create vectors for each chunk. Supports semantic search
Economical	Uses keyword indexing. Faster, no embedding token cost

🚨 WARNING: Changing the Index Method will trigger re-indexing of all documents. This process may take time depending on data volume. ## Change Embedding Model If using the High Quality index method, you can change the Embedding Model: 3\. Go to Knowledge Base Settings 4\. In the Embedding Model section, select a new model 5\. Click Save ⚠️ IMPORTANT: Changing the Embedding Model will re-embed all chunks. Ensure the new model has its API key configured in Settings > Model Providers. ## Configure Retrieval Settings Adjust retrieval parameters:


Setting	Description
Retrieval Mode	Semantic Search, Keyword Search, or Hybrid
Weight Settings	Semantic vs Keyword weight (when using Hybrid)
Top K	Maximum chunks to return
Score Threshold	Minimum similarity score
Rerank Model	Enable/disable and select Rerank model

See details at: \[Index Method & Retrieval Settings]\(./04-index-retrieval-settings.md) ## Knowledge Base Information In Settings, you can also: · Rename the Knowledge Base · Update description · View statistics: Total documents, total chunks, storage used · View linked applications · Delete Knowledge Base (irreversible action) 🛑 CAUTION: Deleting a Knowledge Base permanently removes all documents, chunks, and configurations. Linked applications will lose their knowledge connection. This action CANNOT be undone. *📖 Previous: \[Metadata]\(./09-metadata.md) · Next: \[Test Retrieval]\(./11-test-retrieval.md)* --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.clickai.vn/clickai-docs/clickai-docs-en/database/manage-knowledge-settings.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
