Please note: as of ElasticPress 4.0.0 trunk is the stable branch, built assets were removed from the develop branch, a ZIP with the plugin and its built assets are available on the GitHub Releases page, and will include a build script should you want to build assets from a branch. As such, please ensure you have updated any references you have from master to trunk or to GitHub releases depending on whether you require built assets or not.

Overview

ElasticPress, a fast and flexible search and query engine for WordPress, enables WordPress to find or “query” relevant content extremely fast through a variety of highly customizable features. WordPress out-of-the-box struggles to analyze content relevancy and can be very slow. ElasticPress supercharges your WordPress website making for happier users and administrators. The plugin even contains features for popular plugins.

Upgrade notices

3.5

Search Algorithm Upgrade Notice: Version 3.5 includes a revamp of the search algorithm. This is a backwards compatibility break. If you'd like to revert to the old search algorithm, you can use the following code: add_filter( 'ep_search_algorithm_version', function() { return '3.4'; } );. The new algorithm offers much more relevant search results and removes fuzziness which results in mostly unwanted results for most people. If you are hooking in and modifying the search query directly, it's possible this code might break and you might need to tweak it.

4.0.0

Note that ElasticPress 4.0.0 release removes built assets from the develop branch, replaced master with trunk, added a ZIP with the plugin and its built assets in the GitHub Releases page, and included a build script should you want to build assets from a branch. As such, please plan to update any references you have from master to trunk or to GitHub Releases depending on whether you require built assets or not.
