Search

Elasticsearch is a powerful search and analytics engine, but optimizing it for production requires understanding indexing strategies, query patterns, and cluster configuration. This guide covers essential optimization techniques. Cluster architecture Node roles Configure nodes with specific roles: # Master node node.roles: [master] # Data node node.roles: [data] # Ingest node node.roles: [ingest] # Coordinating node (default) node.roles: [] # No specific role Shard strategy Primary shards: Set at index creation (cannot be changed) ...

Elasticsearch is powerful for search. Here’s how to get started. Basic Operations Create Index await client.indices.create({ index: 'users', body: { mappings: { properties: { name: { type: 'text' }, email: { type: 'keyword' }, age: { type: 'integer' } } } } }); Index Document await client.index({ index: 'users', id: '1', body: { name: 'John Doe', email: '[email protected]', age: 30 } }); Search const result = await client.search({ index: 'users', body: { query: { match: { name: 'John' } } } }); Best Practices Design mappings carefully Use appropriate analyzers Optimize queries Monitor cluster health Backup regularly Conclusion Master Elasticsearch for powerful search! 🔍
