🔍 Search Limitations

Currently, the ePrint Archive's search API endpoint is not publicly available, so this server uses RSS feed filtering for search functionality. This means:

• ✅ Search works within recent papers (last ~100 papers from RSS)
• ⚠️ Historical search is limited
• 🔄 We're working on implementing full search capabilities
