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
