The risks section lists potential issues but lacks corresponding mitigation strategies. Each identified risk should include specific mitigation approaches to provide actionable guidance for implementation.

Suggested change

	- Breaking changes to existing search implementations
	- Performance degradation with complex search criteria
	- Increased API load with new search features
	- Browser compatibility issues with new UI components
	- State management complexity with additional features
	- Breaking changes to existing search implementations
	- **Mitigation:** Ensure backward compatibility by maintaining legacy API endpoints and providing thorough regression testing. Communicate changes clearly in release notes and documentation.
	- Performance degradation with complex search criteria
	- **Mitigation:** Optimize search algorithms, implement query caching, and monitor performance metrics. Conduct load testing to identify bottlenecks.
	- Increased API load with new search features
	- **Mitigation:** Implement rate limiting, caching, and optimize API queries. Scale backend resources as needed and monitor API usage.
	- Browser compatibility issues with new UI components
	- **Mitigation:** Test UI components across supported browsers using automated tools and manual testing. Use polyfills and fallback styles where necessary.
	- State management complexity with additional features
	- **Mitigation:** Refactor Redux store structure for scalability, use middleware for side effects, and document state transitions. Provide training and code reviews for maintainers.
