ElasticSearch Essentials 3.17.10

• Fix incorrect lifespan for similar thread cached keys
• If using Redis, similar thread cache keys are purged by the installer. For other cache backends the cache must be manually flushed

• Fix xf-rebuild:search-bulk not respecting batch-size or worker count CLI options

• Fix using title boost would result in search not searching the expected fields.

• Force global namespace for functions which are known to be optimizable to bytecode in php
• Apply title/exact title boost when scoring 'relevancy' for auto-complete

• 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
• Allow non-moderator users with global "View deleted threads / posts" permission to search for deleted content
• Reduce amount of data loaded when viewing a user's "Post Area" profile tab
• Fix "Only search deleted" search feature not working
• Fix "Push specific content type permission checks into general search" option not working

• Change Post Area to respect the "View threads by others", not just forum visibility

• Fix user's "include deleted" option was not being respected in "find content" search
• Fix incorrect phrase on similar thread widget page
