## Search Syntax

GitHub code search supports advanced syntax:

- **Exact phrase**: `"function authenticate"`
- **File type**: `language:typescript`
- **Path filter**: `path:src/auth`
- **Repository**: `repo:owner/repo-name`
- **Organization**: `org:my-org`
- **Extension**: `extension:ts`

### Examples

Find all TypeScript files with "authenticate"

authenticate language:typescript

Search in specific path

validate path:src/middleware

Search specific repository

JWT repo:my-org/auth-service

Combine filters

async function org:my-org language:javascript

## Tips

- Use specific keywords for better results
- Filter by language to reduce noise
- Search across an organization with `org:`
- Combine with path filters to narrow scope
- Use quotes for exact phrases
- Review multiple implementations for patterns
