I apologize for the amateur mistake. I only deployed the Meilisearch search backend in the production environment and failed to run regression tests on other DB schemas. I mistook successful compilation for a successful deployment.

The PR I created aimed to solve the problem of the Meilisearch automatic indexing queue being flooded, but it is incomplete. It's missing the task queue enqueuing for the BuildIndex task. I plan to refine the Meilisearch task queue later to allow it to accept BuildIndex task submissions. At that time, I might reconsider the regression testing for the recursive folder automatic indexing feature.

Furthermore, the PR @jyxjjj submitted will not affect the functionality of the Meilisearch Task Queue, because once the Meilisearch search function is enabled, msInstance.EnqueueUpdate(parent, objs) queues the task and returns immediately.
