memory = MilvusCloudMemory(
    collection_name="production_knowledge_base",
    embedding_model="text-embedding-3-small",
    dimension=1536,
    index_type="HNSW",  # Best for similarity search
    metric_type="COSINE"
)

# Development configuration
memory = MilvusCloudMemory(
    collection_name="dev_knowledge_base",
    embedding_model="text-embedding-3-small", 
    dimension=1536,
    index_type="IVF_FLAT",  # Balanced performance

## Advanced Features

### Rich Metadata Filtering
```python
# Complex filter expressions
filter_expr = '''
(metadata["category"] == "ai" and metadata["difficulty"] == "advanced") 
or (metadata["topic"] == "embeddings" and metadata["type"] == "concept")
'''

results = memory.search(
    query="advanced AI concepts",
    limit=5,
    filter_expr=filter_expr
)
```

### Hybrid Search
```python
# Combine vector similarity with metadata filtering
results = memory.search(
    query="machine learning algorithms",
    limit=10,
    filter_expr='metadata["category"] in ["ai", "ml"] and metadata["difficulty"] != "beginner"'
)
```

### Collection Management
```python
# Create multiple collections for different domains
medical_memory = MilvusCloudMemory(
    collection_name="medical_knowledge",
    embedding_model="text-embedding-3-small"
)

legal_memory = MilvusCloudMemory(
    collection_name="legal_documents", 
    embedding_model="text-embedding-3-small"
)
```

## Best Practices

1. **Index Selection**: Choose HNSW for similarity search, IVF for large datasets
2. **Metadata Design**: Design rich metadata schema for effective filtering
3. **Batch Operations**: Use batch operations for better throughput
4. **Connection Pooling**: Implement connection pooling for production applications
5. **Error Handling**: Implement robust error handling and retry logic
6. **Monitoring**: Set up monitoring and alerting for performance metrics
7. **Cost Optimization**: Monitor usage and optimize collection configurations
8. **Security**: Follow security best practices for authentication and data access

## Monitoring and Observability

### Key Metrics to Monitor
- Query latency percentiles (p50, p95, p99)
- Query throughput (QPS)
- Error rates and types
- Collection size and growth
- Resource utilization

### Alerting Setup
```python
# Example monitoring integration
import logging

logger = logging.getLogger("milvus_rag")

def monitored_search(memory, query, **kwargs):
    start_time = time.time()
    try:
        results = memory.search(query, **kwargs)
        duration = time.time() - start_time
        logger.info(f"Search completed in {duration:.3f}s, found {len(results['documents'])} results")
        return results
    except Exception as e:
        logger.error(f"Search failed: {e}")
        raise
```

## Troubleshooting

### Common Issues

1. **Connection Errors**: Verify MILVUS_CLOUD_URI and MILVUS_CLOUD_TOKEN. Check network connectivity and firewall settings. Confirm cloud region accessibility.

2. **Performance Issues**: Monitor collection size and index type appropriateness. Check query complexity and filter expressions. Review auto-scaling configuration.

3. **Search Accuracy Issues**: Verify embedding model consistency. Check vector normalization if using cosine similarity. Review index parameters and search parameters.

4. **Quota and Billing Issues**: Monitor usage against plan limits. Review auto-scaling settings. Check billing alerts and notifications.
