Add-ons Search Improvements 2.13.1

• Improve how thread/tickets by others in a category without view-other permission are filtered out of search results when using XFES without ElasticSearch Essentials
• Add PermissionConstraint helper class, designed to simplify implementing XF Search handler's getTypePermissionConstraints function
• Add "Collect search DSL & debug statistics" option (Default off), designed as a developer tool and strongly not recommended for production usage.

• Cleanup add-on description & readme file
• Update XFES dependent option descriptions to include if they require XFES
• Improve styling of 'no results' search result in an overlay
• Fix search result terms do not display when search results are in an overlay
• Fix custom styling triggering "Your changes have been saved." when clicking a member search link

• Fix "Push "View X by others" option being disabled would cause some user information to not be indexed, which had the implicit "rebuild search index" if this setting was then enabled.
  • This fixed conversation search when using Conversation Improvements v2.4.x+
  • Requires a re-index of at least conversations/conversation messages to re-add the missing information.
  • For most sites, disabling the "Push "View X by others" check into XFES" option is not recommended
