9	A fast and flexible search and query engine for WordPress.
10
11	== Description ==
12	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.
13
14	Here is a list of the amazing ElasticPress features included in the plugin:
15
16	__Search__: Instantly find the content you’re looking for. The first time.
17
18	__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.
19
20	__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.
21
22	__Related Posts__: ElasticPress understands data in real time, so it can instantly deliver engaging and precise related content with no impact on site performance.
23
24	__Protected Content__: Optionally index all of your content, including private and unpublished content, to speed up searches and queries in places like the administrative dashboard.
25
26	__Documents__: Indexes text inside of popular file types, and adds those files types to search results.
27
28	__Autosuggest__: Suggest relevant content as text is entered into the search field.
29
30	__Facets__: Add controls to your website to filter content by one or more taxonomies.
31
32	__Users__: Improve user search relevancy and query performance.
33
34	__Comments__: Indexes your comments and provides a widget with type-ahead search functionality. It works with WooCommerce product reviews out-of-the-box.
35
36	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).

54	= 4.2.0 - 2022-05-26 =
55
56	ElasticPress 4.2.0 fixes some bugs and introduces some new and exciting changes.
57
58	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.
59
60	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.
61
62	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.

551	* Fix empty synonym bug.

556
557	= 3.5.0 - 2020-10-20 =
558	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.
559
560	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.

763	* Fix empty autosuggest selector notice
764
765	= 3.0.1 - 2019-05-20 =

767
768	* `wp elasticpress stats` and `wp elasticpress status` commands fatal error fixed.
769	* Add autosuggest selector field default to fix notice.

774	* Don't force document search on REST requests.
775
776	= 3.0 - 2019-05-13 =
777	NOTICE: Requires re-index.
778
779	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.
780
781	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.
782
783	Other Features:
784	* Elasticsearch language setting in admin
785
786	Here are a list of filters/actions removed or changed:
787
788	### Actions Removed:
789
790	* `ep_feature_setup`

856
857	This is a small bug fix release.
858
859	* Removed unnecessary facet JavaScript
860	* Fix facet aggregations warning
861
862	= 2.5.1 - 2018-05-02 =
863	NOTICE: Requires re-index.
864
865	This if a bug fix release. This version requires a re-index as we change the way data is being sent to Elasticsearch.
866
867	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.
868
869	### Bug Fixes
870
871	* Don't pre-strip HTML before sending it to Elasticsearch.
872	* Support PHP 5.2 backwards compat.
873	* Don't show faceting widget if post type doesn't support taxonomy.
874
875	= 2.5 - 2018-04-23 =
876	ElasticPress 2.5 includes a new Facets feature that makes it easy to add high performance content filtering controls to a website.
877
878	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.
879
880	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.
881
882	Here is a detailed list of what's been included in the release:
883
884	### Enhancements
885	* Facets feature
886	* `--post-ids` CLI option to index only specific posts. Props [dotancohen](https://github.com/dotancohen).

907	* Increase maximum Elasticsearch compatibility to 6.1
908
909	= 2.4 - 2017-11-01 =
910	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.
911
912	We also added hooks and filters to ElasticPress that make query logging possible. The [Debug Bar ElasticPress](https://github.com/10up/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.
913
914	Here is a comphrensive list of changes:
915

937	Version 2.3.1-2.3.2 is a bug fix release. Here are a listed of issues that have been resolved:
938
939	* 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.
940	* Fix broken upgrade sync notification.
941	* Properly respect WC product visibility. Props [ivankristianto](https://github.com/ivankristianto). This requires a re-index if you are using the WooCommerce feature.
942
943	= 2.3 - 2017-05-26 =
944	Version 2.3 introduces the Documents feature which indexes text inside of popular file types, and adds those files types to search results. We've also officially added support for Elasticsearch 5.3.
945

974	NOTICE: Requires re-index.
975
976	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.
977
978	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.

987	* 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.
988	* Add support for post_mime_type. Props [Ritesh-patel](https://github.com/Ritesh-patel)
989

1025
1026	### Backward compat breaks:
1027	* Move ep_admin_wp_query_integration to search integration only. EP integration by default is available everywhere.
1028	* Remove `keep alive` setting
1029	* Remove setting to integrate with search (just activate the module instead)
1030	* Back up hosts code removed
1031	* Remove active/inactive state. Rather just check if an index is going on our not.
1032

1035	* Fix `paged` overwriting `offset`
1036	* Fix integer and comma separated string `sites` WP_Query processing. Props [jaisgit](https://github.com/jaisgit).

1041
1042	= 2.0 - 2016-06-01 =
1043	10up ships ElasticPress 2.0 with __radical search algorithm improvements__ and a __more comprehensive integration of WP_Query__. ElasticPress is now even closer to supporting the complete WP_Query API. This version also improves upon post syncing ensuring that post meta updates are synced to Elasticsearch, adds a number of important hooks, and, of course, fixes some pesky bugs.

1116
1117	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:
1118
1119	* `meta.value` (string)
1120	* `meta.raw` (unanalyzed string)
1121	* `meta.long` (unanalyzed number)
1122	* `meta.double` (unanalyzed number)
1123	* `meta.boolean` (unanalyzed number)
1124	* `meta.date` (unanalyzed yyyy-MM-dd date)
1125	* `meta.datetime` (unanalyzed yyyy-MM-dd HH:mm:ss datetime)
1126	* `time` (unanalyzed HH:mm:ss time)
1127
1128	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.
1129
1130	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.
1131
1132	1.7 also contains the following bugs/enhancements:
1133
1134	* (Bug) Prevent missed post indexing when duplicate post dates. Props [lukaspawlik](https://github.com/lukaspawlik)
