{ New } - Subdomain Filtering Feature

✨ New Features

🎯 Subdomain Filtering for Domain Search

• Added subdomains parameter to /search-by-domain endpoint
• Filtering capability: Matches against subdomain portions of URLs (e.g., "auth" in "auth.example.com")
• Key difference from keywords:
  • 🎯 Subdomains: Matches only the subdomain portion of URLs
  • 🔍 Keywords: Matches across the entire URL including paths, parameters, and subdirectories
• Limit: Maximum 5 subdomains per request
• Example usage: {"domains": ["example.com"], "subdomains": ["auth", "admin"]}

🔒 Validation Rules

• Mutual exclusivity: subdomains cannot be used with:
  • keywords or keywords_match parameters
  • external_domains parameter
• Clear error messages for invalid parameter combinations
