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24	__Protected Content__: Optionally index all of your content, including private and unpublished content, to speed up searches and queries in places like the administrative dashboard.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

36	== Frequently Asked Questions ==
37
38	= How does ElasticPress work? =
39
40	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.
41
42	= I have to use an in-house or custom Elasticsearch solution due to policy or institutional requirements. Can you still help? =
43
44	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.

570	= 4.2.0 - 2022-05-26 =
571
572	ElasticPress 4.2.0 fixes some bugs and introduces some new and exciting changes.
573
574	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.
575
576	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.
577
578	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.

1132
1133	= 3.5.0 - 2020-10-20 =
1134	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.
1135
1136	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.

1357
1358	= 3.0 - 2019-05-13 =
1359	NOTICE: Requires re-index.
1360
1361	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.
1362
1363	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.
1364
1365	Other Features:
1366	* Elasticsearch language setting in admin
1367
1368	Here are a list of filters/actions removed or changed:
1369
1370	### Actions Removed:
1371
1372	* `ep_feature_setup`
1373
1374	### Filters changed:

1435
1436	= 2.5.2 - 2018-05-09 =
1437	NOTICE: Requires re-index.
1438
1439	This is a small bug fix release.
1440
1441	* Removed unnecessary facet JavaScript
1442	* Fix facet aggregations warning
1443
1444	= 2.5.1 - 2018-05-02 =
1445	NOTICE: Requires re-index.
1446
1447	This if a bug fix release. This version requires a re-index as we change the way data is being sent to Elasticsearch.
1448
1449	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.
1450
1451	### Bug Fixes
1452
1453	* Don't pre-strip HTML before sending it to Elasticsearch.
1454	* Support PHP 5.2 backwards compat.
1455	* Don't show faceting widget if post type doesn't support taxonomy.
1456
1457	= 2.5 - 2018-04-23 =
1458	ElasticPress 2.5 includes a new Facets feature that makes it easy to add high performance content filtering controls to a website.
1459
1460	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.
1461
1462	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.
1463
1464	Here is a detailed list of what's been included in the release:
1465
1466	### Enhancements

1489	* Increase maximum Elasticsearch compatibility to 6.1
1490
1491	= 2.4 - 2017-11-01 =
1492	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.
1493
1494	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.
1495

1497

1519	Version 2.3.1-2.3.2 is a bug fix release. Here are a listed of issues that have been resolved:
1520
1521	* 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.
1522	* Fix broken upgrade sync notification.
1523	* Properly respect WC product visibility. Props [ivankristianto](https://github.com/ivankristianto). This requires a re-index if you are using the WooCommerce feature.
1524
1525	= 2.3 - 2017-05-26 =
1526	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.

1554
1555	= 2.2 - 2017-02-28 =
1556	NOTICE: Requires re-index.
1557
1558	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.
1559
1560	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.
1561
1562	### Enhancements

1676	NOTICE: Mapping change, requires re-index.
1677

1695
1696	= 1.7 - 2015-12-11 =
1697	NOTICE: Mapping change, requires re-index.
1698
1699	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:
1700
1701	* `meta.value` (string)
1702	* `meta.raw` (unanalyzed string)
1703	* `meta.long` (unanalyzed number)
1704	* `meta.double` (unanalyzed number)
1705	* `meta.boolean` (unanalyzed number)
1706	* `meta.date` (unanalyzed yyyy-MM-dd date)
1707	* `meta.datetime` (unanalyzed yyyy-MM-dd HH:mm:ss datetime)
1708	* `time` (unanalyzed HH:mm:ss time)
1709
1710	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.
1711
1712	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.
1713
1714	1.7 also contains the following bugs/enhancements:
1715
1716	* (Bug) Prevent missed post indexing when duplicate post dates. Props [lukaspawlik](https://github.com/lukaspawlik)
1717	* (Bug) Complex meta types are automatically serialized upon storage.
