OpenSearch Best Practices

Core Principles

• Design indices and mappings based on query patterns
• Optimize for search performance with proper analysis and indexing
• Use appropriate shard sizing and cluster configuration
• Implement proper security with the OpenSearch Security plugin
• Monitor cluster health with Performance Analyzer and optimize queries
• Leverage OpenSearch-specific features: k-NN vector search, neural search, search pipelines, ISM

Index Design

Mapping Best Practices

• Define explicit mappings instead of relying on dynamic mapping
• Use appropriate data types for each field
• Disable indexing for fields you do not search on
• Use keyword type for exact matches, text for full-text search
