Hello Data Center Community,
Happy Data Center Love Month!
I’m Anubhav, a product manager in Atlassian Data Center and I am excited to announce a new enhancement in Confluence designed to address the challenges of slow search performance, particularly with increase in usage and growth in instance size.
Confluence uses Lucene's search library for powering search as default. Lucene, while a robust low-level search library, is not inherently designed to be scale-resilient. This limitation of Lucene becomes more apparent in large instances.
Enter: OpenSearch
OpenSearch is a popular enterprise-grade dedicated search platform that creates a powerful search capability based on distributed processing architecture backed by the robustness of Lucene’s search library.
With the latest Confluence Data Center 9.0 release we now support OpenSearch if you opt-in to switch from the default Lucene based search implementation.
Search in Confluence is now faster:
Our internal performance benchmarking results show OpenSearch is ~4.5x faster than a comparable Lucene-based search and this performance gain only widens with large dataset.
The results:
We tested this on an internal 3 node Confluence instance for benchmarking a 36GB index using Lucene(8 CPU, 32GB RAM) against OpenSearch(2 CPU, 16 GB RAM).
Its not just search that benefits from this feature, below are several reasons for why we believe this is a game changer when it comes to overall Confluence performance experience for our large enterprise customers:
-
Better performance - Search is faster and other functions that depend on Lucene access for e.g. page moves, may experience gains
-
Scale with confidence - As your organization grows in size and scale, take advantage of OpenSearch’s horizontal scaling capabilities and let Confluence grow with you.
-
Reduced overhead - Simplified index management lowers overall Confluence resource consumption.
-
High availability - Search without interruption on clustered OpenSearch instances during reindexing.
Our exploration and thorough tests have confirmed that OpenSearch can significantly improve scale related performance issues, however we also understand that switching to OpenSearch may not be immediate for some customers.

OpenSearch is not the default search platform for Confluence.
To begin to use it, you will need to setup and configure it as first-step.

Search is a core function for any enterprise knowledge management solution and the wide adoption of Confluence has meant that we keep enhancing and improving the Confluence Search features for our customers. In the recent past we introduced space re-index with Confluence DC 8.4 to ensure users can promptly access the most up-to-date content and modifications in real-time fostering a seamless and uninterrupted collaboration experience among teams.
For more details on OpenSearch refer to Confluence DC 9.0 release notes.
