System Usage Limits
To ensure long-term system stability and a fair experience for all users, we have set some necessary usage limits:
Reasons for Limits:
- Massive Data Volume - The system contains hundreds of millions of data records, and each search consumes significant computing resources
- Server Load Considerations - Frequent high-concurrency search requests can affect overall system performance
- Preventing Data Abuse - Limiting search frequency effectively prevents bulk data scraping
