ElasticSearch Essentials 3.15.12

• Require minimum version of XF2.1.8+
• Improve handling of int-like options for CLI bulk search indexer (php cmd.php xf-rebuild:search-bulk)
• On the advanced search page, automatically support include/exclude tags for taggable content, or content which groups to taggable content.
• On searching with include/exclude tags, only search content which supports tags.
  • This results in only searching threads when searching from the 'search threads' tab when normally it would search threads and posts.
  • Add option "Project container tags into content tags", this allows tag-based search to work on posts rather than just threads.
  • Changing this option will require re-indexing!
• When autocomplete is open, do not close search menu when escape key is pressed
• Move autocomplete result row format into XF template system, and use menu-row/contentRow/etc to better match native styling
• Add search option "Search only containers", this allows only searching threads vs searching threads & posts
  • Add style property "Enable 'Search only containers' search option" to control if this option is displayed
  • Add style property "Default 'Search only containers' search option" to control if this is default selected (default is unselected)
• Work-around XF design limitation where a search URl operating on "thread" content type ignores constraints that "post" supports
• Enhance search/member endpoint to support c[newer_than] URL argument
• Add per-content-type limits for search auto-complete, this may cause additional ElasticSearch queries

• Fix "[E_NOTICE] Undefined index: stemming_language"
• Fix "Search titles only" feature incorrectly looking at 'exact message body' if that feature is enabled

• Fix "Display to mobile users" in similar thread widget being in-effective
• Fix that extended Enhanced search - Index configuration options did not apply on initial configuration
• Fix installer upgrade path migrating similar thread widget options (Applies for pre-v3.6.x upgrades), please check similar thread widget options.
• Improve php cmd.php xf-rebuild:search-bulk to implement multi-threaded indexing for all search types
  • This can significantly speed-up search re-indexing if a large number of CPU cores are available.
  • An example is re-indexing ~40 million odd posts in ~30 minutes vs +6 hours with enough CPU and NVMe SSDs
• Add options for "Exact text search - title"/"Exact text search - body" options (under Enhanced search configuration). Requires re-indexing to apply.
  Exact text search indexes text with and without word-stemming, and thus increases the search index size.
  Searching for quoted text to match non-stemmed words, and will ignore stemmed words
• Move standard auto-complete icon into template svElasticSearchEssentials_user_auto_complete_icon

• Fix that "postings" profile tab would never show deleted content, by supporting moderator "Include deleted" search option

• Reduce amount of data loaded when viewing a user's "Post Area" profile tab
• Fix "Only search deleted" search feature not working
