Improving search performance

OpenSearch offers several ways to improve search performance, from foundational optimizations to specialized techniques:

• Store frequently accessed data in memory with caching for faster retrieval.

• Search segments concurrently using concurrent segment search for better resource utilization.

• Control shard selection for optimized query routing with search shard routing.

• Run resource-intensive queries asynchronously with asynchronous search to avoid timeouts.

• Improve aggregation performance using a star-tree index for analytical workloads.
