- removed `internalLinking` GA labs flag
- renamed search providers to `flex` and `basic`
- keeps old search provider around as it can handle non-English languages unlike the faster flex provider
- updated `search` service to switch from `flex` to `basic` when the site's locale is not english
- bumped Koenig packages to switch from a feature flag for toggling internal linking features to the presence of the `searchLinks` function in card config
- updated tests to correctly switch between flex and basic providers in respective suites

- moved current search into new `search-provider` service and updated `search` service to use the provider service internally
- added `search-provider-beta` service
- uses `flexsearch` as the underlying index for each document so we have better indexing and matching compared to the naive exact-match search we had previously
- adds `excerpt` matching for posts and pages
- keeps results output the same as the original search provider
- added `internalLinkingSearchImprovements` labs flag so we can test this internally before reaching our internal linking beta testers
- updated `search` service to switch between providers based on labs flag
closes https://linear.app/tryghost/issue/MOM-80
- bumps @tryghost/koenig-lexical to add support for search result metadata in internal links as well as some improvements to the internal linking UI/UX
- updates search service to fetch and expose additional `visibility` and `published_at` fields for post/page resources
- updates `searchLinks` method passed to editor to decorate the search results with appropriate meta text and icon based on publish date, post visibility and member settings
closes https://linear.app/tryghost/issue/MOM-106
- the search results can hide any matching authors/tags due to them appearing after matching posts which is typically a longer list that needs scrolling through
- changed the order to list matched authors and tags before posts, this matches the behaviour in our front-end search

The 30s search content expiry didn't really make sense and caused unnecessary delays and server load now that search will be more widely used within the editor.
- replaced concept of time-based expiry with explicit expiry
- content still fetched on query if not already loaded or marked as stale
- added `.expireContent()` method on search service to allow explicit expiry
- updated editor to pre-fetch search content when not already loaded or marked as stale
- removes delay when first using internal linking search inside the editor
- updated post model to expire search content on save
- expires on published post save or delete
- expires on publish and unpublish
- updated tag model to expire content on create/save/delete
- only expires when name or url is changed
- updated user model to expire on save/delete
- only expires when name or url is changed
- does not handle creation because that's done server-side via invites
closes https://linear.app/tryghost/issue/MOM-103
- the `yield waitForProperty(...)` call that was supposed to return once the content refresh occurred never reached a valid state so the first search query (or any later query) where a content refresh occurred would never resolve causing search to look like it had stalled
- switched to waiting for the last running task to resolve instead which does the same as the previous code intended
- exported the `getPosts` request handler function so in mirage config so we can re-use it with different timing on a per-case basis
no issue
- updated search to add `status` to the search results
- added filtering to the editor's `searchLinks()` method
- prevented TaskCancellation errors being thrown from the search task being cast to a Promise
ref https://linear.app/tryghost/issue/MOM-1
- renamed `searchable` to `groupName` so it better matches usage and avoids leaking internal naming to external clients
- added `url` to the fetched data for each data type as the editor will want to use front-end URLs in content
- added acceptance tests to help avoid regressions as we further generalise/optimise the search behaviour
