Because data is fetched over the network from remote clusters, adding communication delay. -> Option AQuick Check:
Network fetch causes latency in cross-cluster search [OK]
Quick Trick: Network calls add latency to cross-cluster search queries [OK]
Common Mistakes:
MISTAKES- Thinking data is copied locally before search
- Assuming caching is disabled for cross-cluster queries
- Believing query language changes
