# USE KB
|
||
|
|
|
||
|
|
Activate a knowledge base collection for semantic search.
|
||
|
|
|
||
|
|
## Syntax
|
||
|
|
|
||
|
|
```basic
|
||
|
|
USE KB "collection_name"
|
||
|
|
USE KB collection_variable
|
||
|
|
```
|
||
|
|
|
||
|
|
## Parameters
|
||
|
|
|
||
|
|
| Parameter | Type | Description |
|
||
|
|
|-----------|------|-------------|
|
||
|
|
| `collection_name` | String | Name of folder inside `.gbkb/` |
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
Loads a knowledge base collection, enabling automatic semantic search for that content. Once active, the LLM searches this collection when answering questions - no explicit search code needed.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
|
||
|
|
### Basic Usage
|
||
|
|
|
||
|
|
```basic
|
||
|
|
USE KB "policies"
|
||
|
|
' Bot now answers questions using policy documents
|
||
|
|
```
|
||
|
|
|
||
|
|
### Multiple Collections
|
||
|
|
|
||
|
|
```basic
|
||
|
|
USE KB "products"
|
||
|
|
USE KB "pricing"
|
||
|
|
USE KB "support"
|
||
|
|
' All three collections searchable
|
||
|
|
```
|
||
|
|
|
||
|
|
### Conditional Loading
|
||
|
|
|
||
|
|
```basic
|
||
|
|
dept = GET user_department
|
||
|
|
IF dept = "HR" THEN
|
||
|
|
USE KB "hr_policies"
|
||
|
|
ELSE IF dept = "IT" THEN
|
||
|
|
USE KB "it_docs"
|
||
|
|
END IF
|
||
|
|
```
|
||
|
|
|
||
|
|
### Dynamic Collection
|
||
|
|
|
||
|
|
```basic
|
||
|
|
topic = HEAR "What topic?"
|
||
|
|
USE KB topic
|
||
|
|
```
|
||
|
|
|
||
|
|
## How It Works
|
||
|
|
|
||
|
|
1. User asks question
|
||
|
|
2. System searches active collections
|
||
|
|
3. Top matching chunks added to LLM context
|
||
|
|
4. LLM generates informed response
|
||
|
|
|
||
|
|
## Collection Structure
|
||
|
|
|
||
|
|
```
|
||
|
|
bot.gbkb/
|
||
|
|
├── policies/ → USE KB "policies"
|
||
|
|
├── products/ → USE KB "products"
|
||
|
|
└── support/ → USE KB "support"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Supported File Types
|
||
|
|
|
||
|
|
PDF, DOCX, TXT, MD, HTML, CSV, JSON
|
||
|
|
|
||
|
|
## Performance
|
||
|
|
|
||
|
|
- Each collection uses ~50MB RAM when active
|
||
|
|
- First search: 100-200ms
|
||
|
|
- Subsequent: 20-50ms (cached)
|
||
|
|
|
||
|
|
**Tip:** Load only what's needed, clear when done.
|
||
|
|
|
||
|
|
## Common Patterns
|
||
|
|
|
||
|
|
### Role-Based
|
||
|
|
|
||
|
|
```basic
|
||
|
|
SWITCH GET user_role
|
||
|
|
CASE "manager"
|
||
|
|
USE KB "management"
|
||
|
|
CASE "developer"
|
||
|
|
USE KB "documentation"
|
||
|
|
CASE "customer"
|
||
|
|
USE KB "products"
|
||
|
|
END SWITCH
|
||
|
|
```
|
||
|
|
|
||
|
|
### With Context
|
||
|
|
|
||
|
|
```basic
|
||
|
|
USE KB "technical_docs"
|
||
|
|
SET CONTEXT "You are a technical expert" AS prompt
|
||
|
|
```
|
||
|
|
|
||
|
|
### With Website
|
||
|
|
|
||
|
|
```basic
|
||
|
|
USE WEBSITE "https://docs.example.com"
|
||
|
|
USE KB "documentation"
|
||
|
|
' Fresh web content now searchable
|
||
|
|
```
|
||
|
|
|
||
|
|
## Error Handling
|
||
|
|
|
||
|
|
```basic
|
||
|
|
TRY
|
||
|
|
USE KB user_requested_kb
|
||
|
|
CATCH
|
||
|
|
TALK "That knowledge base doesn't exist"
|
||
|
|
END TRY
|
||
|
|
```
|
||
|
|
|
||
|
|
