3.5.1

A bug fix release.

Bug fixes:

• Fixes highlighting so that full content is returned instead of only snippets.
• Fix empty synonym bug.
• Only highlight post content, excerpt, and title.

Enhancements:

• Track CLI index in a headless fashion

3.5.0

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.

• Fix default autosuggest selector.

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

2.5.1 - 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.

Added

Fixed

• Support Elasticsearch 6.1 and properly send Content-Type header with application/json. Props @eugene-manuilov.
• Autosuggest event target issue bug. Props @eugene-manuilov.
• Widget init bug. Props @eugene-manuilov.
• Taxonomy sync parameter warning. Props @eugene-manuilov.

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.

2.3.1 - 2017-06-29

Notice

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

Fixed

• Properly respect WC product visibility. Props @ivankristianto.

2.3 - 2017-05-26

• 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) Related posts are now in a widget instead of automatically being appending to content.

• 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.
• Support for post_mime_type. Props @Ritesh-patel
• 'number' param to satisfy WP v4.6+ fixing get_sites call. Props @rveitch

2.0 - 2016-06-01

1.9 - 2016-05-17

Overview

• ElasticPress 1.9 adds in an admin UI, where you can set your Elasticsearch Host and run your index command, without needing to us WP-CLI. Version 1.9 also adds in some performance improvements to reduce memory consumption during indexing. Full list of enhancements and bug fixes:

Added

Overview

• ElasticPress 1.8 adds a bunch of mapping changes for accomplishing more complex WP_Query functions such as filtering by term id and sorting by any Elasticsearch property. Version 1.8 also speeds up post syncing dramatically through non-blocking queries. Full list of enhancements and bug fixes:

Added

• Filter around the search fuzziness argument. Props @dkotter.
• Make post indexing a non-blocking query. Props @cmmarslender.
• Log queries for debugging. Makes ElasticPress Debug Bar plugin possible.

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)
• meta.boolean (unanalyzed number)
• meta.date (unanalyzed yyyy-MM-dd date)
• meta.datetime (unanalyzed yyyy-MM-dd HH:mm:ss datetime)
• time (unanalyzed HH:mm:ss time)
• Index posts according to post type. Props @sc0ttkclark

Fixed

• Prevent missed post indexing when duplicate post dates. Props @lukaspawlik
• Complex meta types are automatically serialized upon storage.
