    3. Add performance benchmarks
    4. Create test scenarios
    class TestScenario:
    async def run_scenario(self):
        # Upload test documents
        docs = await self.upload_test_documents()
        
        # Perform searches
        results = await self.perform_test_searches()
        
        # Validate results
        self.validate_results(results)

2. Performance Optimization
