Unreleased

4.3.0 - 2022-08-31

ElasticPress 4.3.0 fixes some bugs and introduces some new and exciting changes.

WooCommerce Product Variations SKUs are now a publicly searchable field. Site administrators wanting to allow users to search for their product variations SKUs can enable it in the Search Fields & Weighting Dashboard, under Products. If a user searches for a variation SKU, the parent product will be displayed in the search results.

The last ElasticPress sync information is now available in WordPress's Site Health. If you want to check information like the date of the last full sync, time spent, number of indexed content, or errors go to Tools -> Site Health, open the Info tab and click on ElasticPress - Last Sync.

Facets received some further improvements in this version. In addition to some refactoring related to WordPress Block Editor, ElasticPress 4.3.0 ships with an experimental version of a Facet By Meta block. With that, users will be able to filter content based on post meta fields. If you want to try it, download and activate this plugin. Do you have an idea of an enhancement? Search in our facets label in GitHub and if it is not there yet, feel free to open a new issue. We would love to hear new ideas!

4.2.0 - 2022-05-26

ElasticPress 4.2.0 fixes some bugs and introduces some new and exciting changes.

The sync functionality had its JavaScript refactored. Timeouts, memory limits, and general errors are now properly handled and do not make the sync get stuck when performed via the WP-CLI index command. There is also a new get-last-sync WP-CLI command to check the errors and numbers from the last sync.

We've improved the admin search experience for sites using both WooCommerce and Protected Content. Previously, WooCommerce was processing that screen with two different queries, and EP was used only in one of them. Now, it will be only one query, fully handled by ElasticPress. Users wanting to keep the previous behavior can do so by adding add_filter( 'ep_woocommerce_integrate_admin_products_list', '__return_false' ); to their website's codebase.

Facets are now available through a WordPress block. If you are using the Full Site Editing feature, you can now add ElasticPress Facets to your theme with just a few clicks! This block has been introduced with a simplified user interface to enable compatibility with Full Site Editing and will continue to be iterated and improved in future versions of the plugin.

Added

Changed

  • Facets widgets rendered by a separate class. Props @felipeelia via #2712.
  • Deprecated ElasticPress\Feature\Facets\Widget::get_facet_term_html() in favor of ElasticPress\Feature\Facets\Renderer::get_facet_term_html(). Props @felipeelia via #2712.
  • Log errors and remove indexing status on failed syncs. Props @felipeelia via #2748.
  • Refactored Sync page JavaScript. Props @JakePT via #2738.
  • Updated admin scripts to use WordPress's version of React. Props @JakePT via #2756.
  • WooCommerce products list in the Dashboard now properly leverages ElasticPress. Props @felipeelia via #2757.
  • Removed Instant Results' dependency on @wordpress/components and @wordpress/date. Props @JakePT and @felipeelia via #2774.
  • (Protected Content) Password-protected posts are only hidden on searches. Props @felipeelia, @JakePT, and @burhandodhy via #2780.
  • The plugin is now available via Composer without any additional steps required. Props @felipeelia, @jeffpaul, and @johnbillion via #2799.

Bug fixes:

  • Only highlight post content, excerpt, and title.

Enhancements:

  • Track CLI index in a headless fashion

3.5.0 - 2020-10-20

Version 3.5 is a very exciting release as it contains two major new features: a synonym dashboard and search term result highlighting. The synonym dashboard empowerers users to create synonym lists for searches. For example. searching "New York City" would return contain with "NYC". Search term highlighting will underline and add a CSS class to keywords within content that matches the current search.

The new version also 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.

Bug fixes:

  • Fix default autosuggest selector.
  • Fix facet feature $_GET parameter naming collision.
  • Autosuggest a11y fixes. Props amesplant.
  • Check $feature type before calling Feature methods. Props pdewouters.

3.0 - 2019-05-13

Notice

  • Requires re-index

Overview

  • 3.0 is a refactor of ElasticPress for modern coding standards (PHP 5.4 required) as well as the introduction to indexables. Indexables abstracts out content types so data types other than post can be indexed and searched. 3.0 includes user indexing and search (integration with WP_User_Query). User features require at least WordPress version 5.1.
  • The refactor changes a lot of ElasticPress internals. The biggest change is the feature registration API has completely changed. Now, new features should extend the ElasticPress\Feature class rather than calling ep_register_feature. Older features should be backwards compatible.

Added

  • Elasticsearch language setting in admin

Changed

  • ep_post_sync_kill filter removed $post_args argument.
  • posts-per-page changed to per-page for WP-CLI index command.

Removed

  • ep_feature_setup action

2.8.2 - 2019-03-26

Added

  • WooCommerce product attributes as facets.

Removed

  • Unnecessary facet JavaScript

Fixed

  • Facet aggregations warning

2.5.1 - 2018-05-02

Notice

  • Requires re-index as we change the way data is being sent to Elasticsearch.
  • It's also worth noting for ElasticPress version 2.5+, the Facets feature, which is on by default, will run post type archive and search page main queries through Elasticsearch. If Elasticsearch is out of sync with your content (possible in rare edge cases), this could result in incorrect content being shown. Turning off Facets would fix the problem.

Fixed

  • Don't pre-strip HTML before sending it to Elasticsearch.
  • Support PHP 5.2 backwards compat.
  • Don't show faceting widget if post type doesn't support taxonomy.

2.5 - 2018-04-23

Overview

  • 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.

Fixed

  • Related posts not showing up bug.

2.4.1 - 2018-01-30

Added

  • Increase maximum Elasticsearch compatibility to 6.1

Fixed

2.4 - 2017-11-01

Overview

  • 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.

Added

  • Autosuggest feature
  • Hooks for query log functionality in Debug Bar ElasticPress
  • Support WP_Query fields parameter. Props @kallehauge.

2.3.2 - 2017-06-30

Fixed

  • Cache ES plugins request. This is super important. Instead of checking the status of ES on every page load, do it every 5 minutes. If ES isn't available, show admin notification that allows you to retry the host.

2.3.1 - 2017-06-29

Notice

  • This requires a re-index if you are using the WooCommerce feature.

Fixed

2.3 - 2017-05-26

Overview

  • Prevent EP from auto-activating a feature that was force deactivated
  • Prevent massive field Elasticsearch error when indexing large strings

2.2 - 2017-02-28

Notice

  • Requires re-index

Overview

  • 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.

Added

  • (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 appending to content.

  • 'number' param to satisfy WP v4.6+ fixing get_sites call. Props @rveitch

Fixed

  • Back compat with old ep_search function.

2.0.1 - 2016-08-02

Fixed

  • Don't load settings on front end. This fixes a critical bug causing ElasticPress to check the Elasticsearch connection on the front end.

2.0 - 2016-06-01

1.7 (Mapping change, requires reindex) - 2015-12-11

Overview

  • ElasticPress 1.7 restructures meta mapping for posts for much more flexible meta queries. The post_meta Elasticsearch post property has been left for backwards compatibility. As of this version, post meta will be stored in the meta Elasticsearch property. meta is structured as follows:
  • When querying posts, you will get back meta.value. However, if you plan to mess with the new post mapping, it's important to understand the intricacies.
  • The real implications of this is in meta_query. You can now effectively search by meta types. See the new section in README.md for details on this.

Added

  • meta.value (string)
  • meta.raw (unanalyzed string)
  • meta.long (unanalyzed number)
  • meta.double (unanalyzed number)

  • Add WP_Query integration on init rather than plugins loaded. Props @adamsilverstein
  • Properly set global post object post type in loop. Props @tott

  • Abide by the exclude_from_search flag from post type when running search queries. Props @ryanboswell
  • Correct mapping of post_status to not_analyzed to allow for filtering of the search query (will require a re-index). Props @jonathanbardo
