Description

In T395414: Link Recommendations are not available on the beta cluster, I discovered that updating weighed tags in beta does not work when wgCirrusSearchEnableEventBusWeightedTags is disabled. This breaks Add-Link-Structured-Task, and Beta is an important part of QA for the Growth Team.

Since turning wgCirrusSearchEnableEventBusWeightedTags off in beta made the weighed tags updates go ahead, I made that change on beta only as a stop-gap to unblock the Growth team (https://gerrit.wikimedia.org/r/c/operations/mediawiki-config/+/1151608).

I'm unsure if the EventBus approach is supposed to work on beta as well, or whether that is something we only intend to use in production. I'm creating this task for the #search-team, so that it can review my actions and determine whether any other follow-up is necessary.

Gehel edited projects, added Discovery-Search (2025.05.24 - 2025.06.13); removed Discovery-Search.

The EventBus approach is not supposed to work on beta since we don't have the infrastructure there to run the same system.
