ElasticSearch Essentials 3.17.10

• Fix "Redirect to top validated suggestion" option was inverted.
• Fix "Redirect to top validated suggestion" could redirect to non-validated suggestions if "Validate Suggestions" was disabled

• Fix regression in v3.13.1 causing most forums to be skipped from autocomplete/similar search

• Improve autocomplete results by excluding forums where the user lacks "view content" permission (aka they can see titles but not content).
• Fix "Enable suggestions only for the first page of search results" was not applying for low search result count
• Harden displaying "no results found" for search results (do not risk using cached search results).
  This add-on is not vulnerable to leaking cached search results like Search Improvements v2.8.0/v2.8.1 did.
  However if Search Improvements v2.8.0/v2.8.1 was installed then the site was still vulnerable to this issue

• Improve detection of 'empty results' for various search result options (Search Improvements v2.8.0+ compatibility)
• Add "Collapsible similar content" style property option (for this add-on's widget), allowing the similar thread box to be collapsed by the user and remembered via a cookie
• Adjust various search option defaults:
  • Autocomplete sort type: Relevance
  • Enable Autocomplete for mobiles: true
  • Apply content weights to auto-complete: true
  • Weight by reply count (threads): 0.4
  • Exact text search - body: true
  • Exact title boost: 2
  • Title boost: 1.4

• Fix uninstaller (Missing function argument)
• Fix XFRM support ("Unknown filter type unit" error)

• Initial php 8.2 compatibility update
• If installed, require Search Improvements v2.6.0+
• Support Search Improvements v2.7.0+ search term display
• Add 'include deleted' status to URL constraints
• Do not autoconfigure the ESE similar thread widget for new installs with a position as XFES ships with one.
• Avoid triggering similar thread lookups for titles with single character titles

• Improve compatibility with 3rd party add-ons which implement a search handler but not the entity handler for the backing type

• Fix unexpected additional searches on no results for searches with no keywords could be triggered when "Enable suggestions only for the first page of search results" is enabled

Users who had thier licence expire since the last update and this update, have had a licence expension applied.

• Fix not removing 3rd party content types a user can't search from general search, resulting in search result pages showing less results than expected, which cam be used as an oracle to determine if a phrase exists.
• Fix possible case where 'recent content' tab could leak posts from forums which users did not have 'view threads by others' permission due to incomplete permission checks

• Workaround for XF bug where search results are fetched more than once
• Fix "Call to undefined method canViewSimilarContents()" during add-on upgrade
• Implement MySQL-base caching for similar thread results, as otherwise ElasticSearch may be overloaded by uncached queries
  • Redis/Memcache-based caching is still strongly recommended.
• Improve autocomplete & similar thread performance for forums with large number of nodes by avoiding fetching the entire node list every autocomplete/similar threads query.
