David Bean I used the Fulltext Search within MySQL for some time, but ultimately ended up moving to Meilisearch as it provided more functionality. However, the Fulltext Search within the database got me very far for many years.
While it make not be a big deal for one item, I've worked on many projects that deviated from the standard CRUD style and it was okay at first until it became too much. One or two additional actions may not be a big deal, but after that it starts to become a mess. Personally, I'd rather namespace the items and keep the controllers smaller.
