## Problem description

After the search-meilisearch plugin is configured normally, the meilisearch search function can be used (new questions and replies to questions can be searched), but when `blocking` is turned on, the content of new questions can be searched, but replies to the corresponding questions cannot be searched. When `blocking` is not turned on, both questions and answers can be searched.

### Summary

When the search-meilisearch plugin is turned on with `blocking`, answers to new questions cannot be searched.
