Change Details

# Motivation Once the technical approach from T250139 is confirmed, It should be implemented in code. So the core should be changed in a way to delegate the implementation to extensions via Hooks. # Expected result * list of additional fields should be added to configuration (SearchHandlerConfigOptions ). * Hooks should be called to provide a possibility to define implementation in extensions.

# Motivation Once the technical approach from T250139 is confirmed, It should be implemented in code. * Add 2 hooks (naming TBD on gerrit review): "provideThumbnailsForPages" and "provideDescriptionForPages". * Contract for hooks the following: [ &$pageIds ], where $pageIds is an array of pageId=>null. Provided should amend it setting a value for a certain pageId instead of null. * provideThumbnailsForPages should provide objects of type ThumbnalInfo (exact type or name of class, or whatever it is TBD) * provideDescriptionForPages should provide objects of type string * SearchHandler (or some class in the 'core') should serialize the info provided by hooks in a proper way and augment the proper fields if the results with it. # Expected result * Hooks should be introduced * Tests that verifies that hooks are called in a proper way should be added * Augmentation logic that merges results with info provided from hooks should be implemented * Bot integration and Unit Tests that verifies the augmentation logic should be provided
