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__: With ElasticPress, filtering WooCommerce product results is fast and easy. Your customers can find and buy exactly what they're looking for, even if you have a large or complex product catalog.
__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__Protected Content__: Optionally index all of your content, including private and unpublished content, to speed up searches and queries in places like the administrative dashboard.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.
__Filters__: 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).
= I have a problem with the plugin. Where can I get help? =
If you have identified a bug or would like to suggest an enhancement, please refer to our [GitHub repo](https://github.com/10up/ElasticPress). We do not provide support here at WordPress.org forums.
If you are an ElasticPress.io customer, please open a ticket in your account dashboard. If you need a custom solution, we also offer [consulting](https://www.elasticpress.io/elasticpress-consulting/).
= Where do I report security bugs? =
You can report any security bugs found in the source code of ElasticPress through the [Patchstack Vulnerability Disclosure Program](https://patchstack.com/database/vdp/elasticpress). The Patchstack team will assist you with verification, CVE assignment and take care of notifying the developers of this plugin.
= 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).
= I really like ElasticPress! Can I contribute? =
For sure! Feel free to submit ideas or feedback in general to our [GitHub repo](https://github.com/10up/ElasticPress). If you can, also consider sending us [a review](https://wordpress.org/support/plugin/elasticpress/reviews/#new-post).

= 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](https://raw.githubusercontent.com/10up/ElasticPress/develop/tests/cypress/wordpress-files/test-plugins/elasticpress-facet-by-meta.php). Do you have an idea of an enhancement? Search in our [`facets`](https://github.com/10up/ElasticPress/labels/module%3Afacets) 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.

**ElasticPress 4.0 contains some important changes. Make sure to read these highlights before upgrading:**
* This version requires a full reindex.
* It introduces a new search algorithm that may change the search results displayed on your site.
* A new feature called "Instant Results" is available. As it requires a full reindex, if you plan to use it, we recommend you enable it first and reindex only once.
* Users upgrading from Beta 1 need to re-save the Instant Results feature settings.
* New minimum versions are:
||Min|Max|
|---|:---:|:---:|
|Elasticsearch|5.2|7.10|
|WordPress|5.6+|latest|
|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).)
