## DirectorySearchTool

The DirectorySearchTool enables semantic search capabilities for directory contents using Retrieval-Augmented Generation (RAG). It processes files recursively within a directory and allows searching through their contents using natural language queries.

## Installation

```bash
pip install 'crewai[tools]'
```

## Usage Example

```python
from crewai import Agent
from crewai_tools import DirectorySearchTool

# Method 1: Initialize with specific directory
dir_tool = DirectorySearchTool(directory="/path/to/documents")

# Method 2: Initialize without directory (specify at runtime)
flexible_dir_tool = DirectorySearchTool()

# Create an agent with the tool
researcher = Agent(
    role='Directory Researcher',
    goal='Search and analyze directory contents',
    backstory='Expert at finding relevant information in document collections.',
    tools=[dir_tool],
    verbose=True
)
```

## Input Schema

### Fixed Directory Schema (when path provided during initialization)
```python
class FixedDirectorySearchToolSchema(BaseModel):
    search_query: str = Field(
        description="Mandatory search query you want to use to search the directory's content"
    )
```

### Flexible Directory Schema (when path provided at runtime)
```python
class DirectorySearchToolSchema(FixedDirectorySearchToolSchema):
    directory: str = Field(
        description="Mandatory directory you want to search"
    )
```

## Function Signature

```python
def __init__(
    self,
    directory: Optional[str] = None,
    **kwargs
):
    """
    Initialize the directory search tool.

    Args:
        directory (Optional[str]): Path to directory (optional)
        **kwargs: Additional arguments for RAG tool configuration
    """

def _run(
    self,
    search_query: str,
    **kwargs: Any
) -> str:
    """
    Execute semantic search on directory contents.

    Args:
        search_query (str): Query to search in the directory
        **kwargs: Additional arguments including directory if not initialized

    Returns:
        str: Relevant content from the directory matching the query
    """
```

## Best Practices

1. Directory Management:
   - Use absolute paths
   - Verify directory existence
   - Handle permissions properly

2. Search Optimization:
   - Use specific queries
   - Consider file types
   - Test with sample queries

3. Performance Considerations:
   - Pre-initialize for repeated searches
   - Handle large directories
   - Monitor processing time

4. Error Handling:
   - Verify directory access
   - Handle missing files
   - Manage permissions

## Integration Example

```python
from crewai import Agent, Task, Crew
from crewai_tools import DirectorySearchTool

# Initialize tool with specific directory
dir_tool = DirectorySearchTool(
    directory="/path/to/documents"
)

# Create agent
researcher = Agent(
    role='Directory Researcher',
    goal='Extract insights from document collections',
    backstory='Expert at analyzing document collections.',
    tools=[dir_tool]
)

# Define task
research_task = Task(
    description="""Find all mentions of machine learning 
    applications from the directory contents.""",
    agent=researcher
)

# The tool will use:
# {
#   "search_query": "machine learning applications"
# }

# Create crew
crew = Crew(
    agents=[researcher],
    tasks=[research_task]
)

# Execute
result = crew.kickoff()
```

## Advanced Usage

### Dynamic Directory Selection
```python
# Initialize without directory path
flexible_tool = DirectorySearchTool()

# Search different directories
docs_results = flexible_tool.run(
    search_query="technical specifications",
    directory="/path/to/docs"
)

reports_results = flexible_tool.run(
    search_query="financial metrics",
    directory="/path/to/reports"
)
```

### Multiple Directory Analysis
```python
# Create tools for different directories
docs_tool = DirectorySearchTool(
    directory="/path/to/docs"
)
reports_tool = DirectorySearchTool(
    directory="/path/to/reports"
)

# Create agent with multiple tools
analyst = Agent(
    role='Content Analyst',
    goal='Cross-reference multiple document collections',
    tools=[docs_tool, reports_tool]
)
```

### Error Handling Example
```python
try:
    dir_tool = DirectorySearchTool()
    results = dir_tool.run(
        search_query="key concepts",
        directory="/path/to/documents"
    )
    print(results)
except Exception as e:
    print(f"Error processing directory: {str(e)}")
```

## Notes

- Inherits from RagTool
- Uses DirectoryLoader
- Supports recursive search
- Dynamic directory specification
- Efficient content retrieval
- Thread-safe operations
- Maintains search context
- Processes multiple file types
- Handles nested directories
- Memory-efficient processing
