You mentioned transitioning from monolith to microservices — was this related to the search?

Transitioning from a monolith to microservices is often associated with various aspects, including search, but not limited to it. In the case of search, the monolith may have had a bottleneck in the performance or scalability of the search functionality. Extracting search into a separate microservice allows for independent optimization, the use of specialized technologies (e.g., Elasticsearch), and also facilitates scaling and updating without affecting other parts of the system.

Thus, the transition was related to search, but also considered the general advantages of microservice architecture: separation of responsibilities, improved support, and development flexibility.
