FAQ

OpenSearch questions, answered.

What is OpenSearch and how is it different from Elasticsearch?+

OpenSearch is an Apache 2.0-licensed search and analytics engine that began as a fork of Elasticsearch. Since 2024 it has been governed by the OpenSearch Software Foundation under the Linux Foundation, and it is available as a managed service on AWS. The two share roots but have diverged in features, plugins and APIs, so the right choice depends on your requirements.

Can OpenSearch power RAG and AI agents?+

Yes. OpenSearch supports k-NN vector search and hybrid search, so it can serve as the retrieval layer for RAG systems and agent tools - often on infrastructure you already run, without adding a separate vector database.

Should I migrate from Elasticsearch to OpenSearch?+

It depends on your priorities: licensing preferences, AWS integration, feature needs and total cost. We run a migration assessment that compares both options against your workload before you commit either way.

How long does an Elasticsearch to OpenSearch migration take?+

Timelines depend on data volume, cluster complexity and downtime tolerance. Simple migrations can complete in days; complex production migrations typically take 2-6 weeks. We plan for zero-downtime cutover with a tested rollback path.

Can you help optimize our AWS OpenSearch costs?+

Yes. We right-size instances and storage, tune index and shard configuration, and implement data lifecycle policies. For GrabJobs, this kind of optimization delivered a 40% infrastructure cost reduction - see the case study for details.

Do you provide ongoing OpenSearch support?+

Yes. We offer ongoing retainers covering monitoring, performance and relevance tuning, security management and troubleshooting for both self-managed OpenSearch and Amazon OpenSearch Service.
