## Overview

The Settings page allows you to adjust Knowledge Base configuration after creation. Some changes may require re-indexing documents.

Access Settings:

1\.     Open the Knowledge Base

2\.     Click the Settings tab (or gear icon)

&#x20;

## Change Index Method

You can switch between 2 index methods:

<table data-header-hidden><thead><tr><th valign="top"></th><th valign="top"></th></tr></thead><tbody><tr><td valign="top">Method</td><td valign="top">Description</td></tr><tr><td valign="top">High Quality</td><td valign="top">Uses Embedding Model to create vectors for each chunk. Supports semantic search</td></tr><tr><td valign="top">Economical</td><td valign="top">Uses keyword indexing. Faster, no embedding token cost</td></tr></tbody></table>

&#x20;

🚨 WARNING: Changing the Index Method will trigger re-indexing of all documents. This process may take time depending on data volume.

&#x20;

## 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.

&#x20;

## Configure Retrieval Settings

Adjust retrieval parameters:

<table data-header-hidden><thead><tr><th valign="top"></th><th valign="top"></th></tr></thead><tbody><tr><td valign="top">Setting</td><td valign="top">Description</td></tr><tr><td valign="top">Retrieval Mode</td><td valign="top">Semantic Search, Keyword Search, or Hybrid</td></tr><tr><td valign="top">Weight Settings</td><td valign="top">Semantic vs Keyword weight (when using Hybrid)</td></tr><tr><td valign="top">Top K</td><td valign="top">Maximum chunks to return</td></tr><tr><td valign="top">Score Threshold</td><td valign="top">Minimum similarity score</td></tr><tr><td valign="top">Rerank Model</td><td valign="top">Enable/disable and select Rerank model</td></tr></tbody></table>

&#x20;

&#x20;

## 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.
