Removal of the sphinx search engine into a microservice. It makes sense?

Question

Laravel

We are going to implement sphinx in a project written in laravel.
should sphinx be moved to a separate microservice outside of this Laravel project?
What are the pros and cons of this solution?

now we are moving one of the tasks into a microservice - this is a worker for processing third-party catalogs that are provided to us by suppliers. A separate microservice reads data from downloaded xml documents, checks for uniqueness by api and updates via resp api if necessary. In order not to give a load on the main server.

And yet - do you need to work with the database of the main project or interact through api?
