# FAISS Search Tool

The FAISS Search Tool enables efficient vector similarity search using Facebook AI Similarity Search (FAISS).

## Usage

```python
from crewai import Agent
from crewai.tools import FAISSSearchTool

# Initialize tool
search_tool = FAISSSearchTool(
    index_type="L2",  # or "IP" for inner product
    dimension=384,    # Match your embedder's dimension
    embedder_config={
        "provider": "fastembed",
        "model": "BAAI/bge-small-en-v1.5"
    }
)

# Add documents
search_tool.add_texts([
    "Document 1 content",
    "Document 2 content",
    # ...
])

# Create agent with tool
agent = Agent(
    role="researcher",
    goal="Find relevant information",
    tools=[search_tool]
)
```

## Configuration

| Parameter | Type | Description |
|-----------|------|-------------|
| index_type | str | FAISS index type ("L2" or "IP") |
| dimension | int | Embedding dimension |
| embedder_config | dict | Embedder configuration |

## Parameters

### index_type
- `"L2"`: Euclidean distance (default)
- `"IP"`: Inner product similarity

### dimension
Default is 384, which matches the BAAI/bge-small-en-v1.5 model. Adjust this to match your chosen embedder model's output dimension.

### embedder_config
Configuration for the embedding model. Supports all CrewAI embedder providers:
- fastembed (default)
- openai
- google
- ollama
