ElasticPress 1.7

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:

• 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)
• meta.time (unanalyzed HH:mm:ss time)

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.

1.7 also contains the following bugs/enhancements:

• (Bug) Prevent missed post indexing when duplicate post dates. Props lukaspawlik
• (Bug) Complex meta types are automatically serialized upon storage.
• (Enhancement) Index posts according to post type. Props sc0ttkclark

Version 1.6.2

This release fixes a few things missed in 1.6.1. 1.6.2 fixes ALL compatibility issues with Elasticsearch 2.0 and should be completely backwards compatible with 1.7.x. Specifically, this version:

• Removes fuzzy_like_this query and uses multi_match instead.
• Uses string instead of array for post type term when there is only one term.

Version 1.6.1

This is a quick bug fix version to account for breaking changes in Elasticsearch 2.0.0. Specifically, the mapping has been adjusted like so:

• Removes the fields field type from object typed fields as they should be called properties.
• Remove path from object field types.

Version 1.6

Version 1.6 contains a number of important enhancements and bug fixes. Most notably, we now support Elasticsearch fallback hosts and the indexing of attachments.

Bug Fixes:

• Clean up PHP Code Sniffer errors. Props chriswiegman
• Properly document Elasticsearch version
• Abide by exclude_from_search instead of public when indexing post types. Props allan23 and ghosttoast.
• Allow posts to be indexed with invalid date values. Props tuanmh
• Support ep_post_sync_kill filter in bulk indexing. Props Stayallive

Enhancements:

• Add blog id to ep_index_name filter. Props kovshenin
• Support post caching in search
• Add recursive term indexing for heirarchal taxonomies. Props tuanmh
• Enable indexing of attachments
• Support fallback hosts in case main EP host is unavailable. Props chriswiegman
• Add ep_retrieve_the_post filter to support relevancy score manipulation. Props matthewspencer
• Make search results filterable. Props chriswiegman

Version 1.5.1

A quick bug release version.

Bug Fixes:

• Prevent notices from being thrown when non-existent index properties are accessed. This was happening for people how upgraded to 1.5 without doing a re-index. Props allan23

Version 1.5

This version includes 16 enhancements and 3 bug fixes across a total of 16 contributors. Only half of these contributors actually work for 10up! The focus of this version is performance. Most notably, ElasticPress queries now completely bypass MySQL yielding huge benefits. In the past ElasticPress was pulling from Elasticsearch but filling in some blanks with MySQL. ElasticPress queries also support the cache_results parameter for storing pulled posts in the object cache.

• Support meta inequality comparisons. Props psorensen.

Version 1.3.1

Changelog:

• Support date in WP_Query orderby.

Version 1.3

• Support meta_query in WP_Query integration
• Improved documentation. Each WP-CLI command has been documented
• Add elasticsearch property to global post object to assist in debugging
• ep_integrate param added to allow for WP_Query integration without search. (Formally called ep_match_all)
• Filter added for post statuses (defaults to publish). Change the sync mechanism to make sure it takes all post statuses into account. Props jonathanbardo
• Bug fix: check if failed post exists in indexing. Props elliot-stocks
• Bug fix: properly check if setup is defined in indexing. Props elliot-stocks
• Bug fix: add WP_Query integration on init rather than plugins loaded. Props adamsilverstein
• Bug fix: Properly set global post object post type in loop. Props tott
• Bug fix: Do not check if index exists on every page load. Refactor so we can revert to MySQL after failed ES ping.
• Bug fix: Make sure we check is_multisite() if --network-wide is provided. Props ivankruchkoff
• Bug fix: Abide by the exclude_from_search flag from post type when running search queries. Props ryanboswell
• Bug fix: Correct mapping of post_status to not_analyzed to allow for filtering of the search query (will require a re-index). Props jonathanbardo

Version 1.2

• Allow number of shards and replicas to be configurable.
• Improved searching algorithm. Favor exact matches over fuzzy matches.
• Query stack implementation to allow for query nesting.
• Filter and disable query integration on a per query basis.
• Support orderby parameter in WP_Query
• (Bug) We don't want to add the like_text query unless we have a non empty search string. This mimcs the behavior of MySQL or WP which will return everything if s is empty.
• (Bug) Change delete action to action_delete_post instead of action_trash_post
• (Bug) Remove _boost from mapping. _boost is deprecated by Elasticsearch.
• Improve unit testing for query ordering.
