Incident leading to incomplete index for title suggestions - https://wikitech.wikimedia.org/wiki/Incidents/2025-05-09_Missing_autocomplete_indices

Title suggestion indices were only partially generated for a few wikis, leading to only some of the pages being searchable through the auto completion search. This was reported by our users. This is related to the current migration to OpenSearch migration.

What else was accomplished in this essential workstream this week?
