A fast and flexible search and query engine for WordPress.

== Description ==

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.

Here is a list of the amazing ElasticPress features included in the plugin:

__Search__: Instantly find the content you’re looking for. The first time.

__Instant Results__: A built for WordPress search experience that bypasses WordPress for optimal performance. Instant Results routes search queries through a dedicated API, separate from WordPress, returning results up to 10x faster than previous versions of ElasticPress.

__WooCommerce__: “I want a cotton, woman’s t-shirt, for under $15 that’s in stock.” Faceted product browsing strains servers and increases load times. Your buyers can find the perfect product quickly, and buy it quickly.

__Related Posts__: ElasticPress understands data in real time, so it can instantly deliver engaging and precise related content with no impact on site performance.

__Protected Content__: Optionally index all of your content, including private and unpublished content, to speed up searches and queries in places like the administrative dashboard.

__Documents__: Indexes text inside of popular file types, and adds those files types to search results.

__Autosuggest__: Suggest relevant content as text is entered into the search field.

__Facets__: Add controls to your website to filter content by one or more taxonomies.

__Users__: Improve user search relevancy and query performance.

__Comments__: Indexes your comments and provides a widget with type-ahead search functionality. It works with WooCommerce product reviews out-of-the-box.

== Frequently Asked Questions ==

= How does ElasticPress work? =

The ElasticPress plugin enables you to connect your WordPress site to the ElasticPress.io service, a SaaS solution that provides an enhanced search experience while reducing load on your WordPress site. For advanced users familiar with both WordPress and Elasticsearch hosting and management, ElasticPress also offers support for plugin functionality using an Elasticsearch instance. Please keep in mind that there are multiple security, performance, and configuration considerations to take into account if you take this approach.

= I have to use an in-house or custom Elasticsearch solution due to policy or institutional requirements. Can you still help? =

If circumstances prevent the use of a SaaS solution like ElasticPress.io, we can also provide [consulting](https://www.elasticpress.io/elasticpress-consulting/) around installation and configuration of custom Elasticsearch instances.

= Where can I find ElasticPress documentation and user guides? =

Please refer to [GitHub](https://github.com/10up/ElasticPress) for detailed usage instructions and documentation. FAQs and tutorials can be also found on our [support site](https://elasticpress.zendesk.com/hc/en-us).

= Is ElasticPress compatible with OpenSearch or Elasticsearch X.Y? =

ElasticPress requirements can be found in the [Requirements section](https://github.com/10up/ElasticPress#requirements) of our GitHub repository. If your solution relies on a different server or version, you may find additional information on our [Compatibility documentation page](https://10up.github.io/ElasticPress/tutorial-compatibility.html).

= 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:__

* E2e tests for the Facets feature. Props [@felipeelia](https://github.com/felipeelia).

|PHP|7.0+|latest|

**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](https://github.com/10up/ElasticPress/releases), 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. (See changes in [#2622](https://github.com/10up/ElasticPress/pull/2622).)

* Fix empty synonym bug.

* 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.

= 3.0 - 2019-05-13 =

NOTICE: Requires re-index.

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.

Other Features:

* Elasticsearch language setting in admin

Here are a list of filters/actions removed or changed:

### Actions Removed:

* `ep_feature_setup`

### Filters changed:

* `ep_post_sync_kill` - Removed `$post_args` argument.

### Other changes:

* `posts-per-page` changed to `per-page` for WP-CLI index command.
