**What is Scan Depth?**
Scan Depth is a setting for the knowledge base that determines how many previous messages the search should analyze for lorebook keywords. This helps the bot retain lorebook content in its memory for a longer period.
**Example:**
* If set to 1, it will only check the last user message for the lorebook keyword.
* If set to 4, it will check the last 4 messages (including bot messages).
