Version 2.5

ElasticPress 2.5 includes a new Facets feature that makes it easy to add high performance content filtering controls to a website.

A new Facets widget enables site administrators to add taxonomy facets to a sidebar (or any widgetized area). When viewing a content list on the front end of the website, the widget will display the name of the taxonomy – e.g. “Categories” – and a checklist with all of its terms. Visitors can narrow down content by selecting terms they are interested in. The Facets feature can be globally configured to narrow results to content that is tagged with any or all of the selected terms. The widget’s front end output contains carefully named CSS classes, so that designers and developers can apply unique styling.

Version 2.5 also includes a number of smaller enhancements and fixes, including official support for Elasticsearch 6.2, and increased functional parity with the WP_Query API.

Here is a detailed list of what's been included in the release:

Enhancements

• Facets feature
• --post-ids CLI option to index only specific posts. Props dotancohen.
• Filter for hiding host setting in dashboard. Props tomdxw.
• Support WP_Query meta query not between comparator.

Bugs

• Disallow duplicated Elasticsearch requests on WooCommerce orders page. Props lukaspawlik
• Fix taxonomy sync object warning. Props eugene-manuilov
• true in is_empty_query terminates ep_query process when it shouldn't. Props yaronuliel

Version 2.4

Version 2.4 introduces the Autosuggest feature. When enabled, input fields of type "search" or with the CSS class "search-field" or "ep-autosuggest" will be enhanced with autosuggest functionality. As text is entered into the search field, suggested content will appear below it, based on top search results for the text. Suggestions link directly to the content.

We also added hooks and filters to ElasticPress that make query logging possible. The Debug Bar ElasticPress plugin now adds a Query Log screen to the ElasticPress admin menu. The Query Log is an extremely powerful tool for diagnosing search and indexing issues.

Here is a comphrensive list of changes:

Version 2.2

Version 2.2 rethinks the module process to make ElasticPress a more complete query engine solution. Modules are now auto-on and really just features. Why would anyone want to not use amazing functionality that improves speed and relevancy on their website? Features (previously modules) can of course be overridden and disabled. Features that don't have their minimum requirements met, such as a missing plugin dependency, are auto-disabled.

We've bumped the minimum Elasticsearch version to 1.7 (although we strongly recommend 2+). The maximum tested version of Elasticsearch is version 5.2. If you are running Elasticsearch outside this version range, you will see a warning in the dashboard.

Enhancements

• (Breaking change) Module registration API changed. See register_module in classes/class-ep-modules.php.
• (Breaking change) Related posts are now in a widget instead of automatically being appended to content.
• (Breaking change) Admin module renamed to Protected Content.
• Admin warning if current Elasticsearch version is not between the min/max supported version. Version 2.2 supports versions 1.3 - 5.1.
• Auto-reindex on versions requiring reindex.
• User friendly admin notifications for ElasticPress not set up, first sync needed, and feature auto activation.
• Protected Content feature applies to all features. This means if Protected Content isn't active, search or WooCommerce integration won't happen in the admin.
• Add support for post_mime_type. Props Ritesh-patel

• Fix recursion fatal error due to oEmbed discovery during syncing. Props ivankristianto

Version 2.1.2

Version 2.1.2 supports Elasticsearch 5.0. We've separated out index mappings for older versions of Elasticsearch to ensure legacy users can still upgrade.

Version 2.1

Version 2.1 marks a huge change in ElasticPress and even what's possible within WordPress. We have transformed the way the plugin works adding a modules system, completely redoing the user interface, adding a number of important WP_Query functional enhancements, and more.

Previously, ElasticPress was a useful plugin for achieving awesome search. Now, ElasticPress is the fast and flexible search and query engine for WordPress. The plugin includes a number of powerful modules, some previously bundled as separate plugins, to supercharge WordPress performance and search. We are extremely excited to launch ElasticPress 2.1. We see it as a framework to completely transform search, performance, and scalability in WordPress.

Here is a list of new features, bug fixes, and backward compatibility breaks in 2.1:

Enhancements

• Redo UI.
• Make plugin modular.
• Remove unnecessary back up hosts code.
• Bundle existing modules into core plugin.
• Support meta_key and meta_value.
• Order by meta_value_num.
• Properly support post_parent = 0. Props tuanmh.
• Add search scope file. Props rveitch.
• Support WP_Query post_status. Props sc0ttclark.

Backward compat breaks:

• Move ep_admin_wp_query_integration to search integration only. ElasticPress integration by default is available everywhere.
• Remove keep alive setting.
• Remove setting to integrate with search (just activate the module instead).
• Back up hosts code removed.
• Remove active/inactive state. Rather just check if an index is going on our not.

Bug fixes

• Fix post__in support.
• Fix paged overwriting offset.
• Fix integer and comma separated string sites WP_Query processing. Props jaisgit.

As always, ElasticPress is free, open source software. We are proud of the contributions every one has provided to make version 2.1 possible.
