A New Era of WordPress Search: Elasticsearch in Beta Now

The WordPress search upgrade you've been waiting for is here. Elasticsearch is now in beta on Pantheon, and you can start using it on your production sites today.

If you're managing a large publishing site, running an eCommerce store, or just tired of bolting on third-party search plugins, this is for you.

Pantheon's Elasticsearch integration handles provisioning, scaling, and uptime so you get enterprise-grade search without the infrastructure overhead.

WordPress Search Has Room to Grow

Managers of content-heavy WordPress sites, you know the struggle. WordPress's native search runs on basic MySQL queries. It works for smaller sites, but as your content library grows– thousands of posts, products, or pages–search starts to struggle.

Relevance ranking? Not really.

Faceted filtering? Good luck.

Typo tolerance? Don’t even ask.

Your visitors expect Google-quality search. MySQL just isn’t built for that, and our Apache Solr integration was a meaningful step up, but came with real friction.

Enter Elasticsearch

Elasticsearch is the industry standard for powering fast, accurate, full-text search at scale. And now it’s available natively on Pantheon for your WordPress sites—fully managed, so you can focus on building great sites instead of running infrastructure.

You get best-in-class search performance, security that meets enterprise standards, and a feature set that’s purpose-built for how WordPress sites actually work.

What You Get

• Blazing-fast full-text search – results in milliseconds, even on sites with tens of thousands of posts.
• Relevance ranking – the most useful results surface automatically, not just the most recent.
• Faceted search & filtering – let visitors narrow results by category, tag, date, custom fields, and more.
• Typo tolerance – fuzzy matching helps visitors find what they’re looking for, even if they misspell it.
• Real-time indexing – content updates are reflected in search results almost instantly.
• Scalable by default – no more slowdowns as your site and content library grow.
• WP_Query offloading – extend Elasticsearch performance benefits across your entire site.

How to Get Started

The Beta is open now. Log in to your Pantheon dashboard, navigate to the site, and look for the Elasticsearch Beta opt-in under Settings > Add-ons.

With the latest version of Terminus, you can also enable Elasticsearch with the new search:enable command.

What’s Next

AI-powered semantic search — ElasticPress 5.3 already supports AI and semantic search features via ElasticPress Labs. Right now, this works with Pantheon Elasticsearch, but it’s BYOT (bring your own tokens), as you’ll need to supply your own API credentials for the AI provider. A more seamless, integrated experience for enabling these features is on our roadmap.

Drupal support — WordPress is just the start. We’re exploring bringing Elasticsearch to Drupal and Next.js sites, too. Submit your interest here.
