Automating OpenSearch Analyzer Synonym Updates: Progress & Challenges

Starting around 3:30 am, this morning’s focus was on refining Ansible-driven automation for updating OpenSearch analyzers and synonym lists, ensuring that changes to the system can be deployed seamlessly without manual intervention. The ultimate goal remains the same: a single-command installation that brings up the entire CodexMCP stack fully configured and ready to go.

One key process remains critical as we continue iterating—reinitializing the system after every change. This ensures that every update, tweak, or fix does not introduce startup failures, allowing for a smooth deployment experience.

Current Challenges & Observations

• The synonym list update process has been automated, but we still need to ensure it functions reliably across multiple indices, particularly mainlogs and kbcomments.
• While we originally suspected OpenSearch 2.18 introduced changes that affected synonym handling, a deeper dive into the changelog analysis is needed to confirm whether these issues stem from the version upgrade or a separate factor.
• Some of the issues may stem from multiple indices attempting to load the same synonyms file simultaneously, causing unexpected failures during index creation.

Next Steps

• Finalize and test the synonym update mechanism across all indices to ensure a fully automated deployment process.
• Continue full system reinitialization testing with each change, ensuring everything works as expected before moving forward.

We’re making solid progress, and once we get the analyzers fully dialed in, this will be one more critical piece of CodexMCP’s automated deployment completed. More updates coming soon!
