Creating Azure Search is an easy task and should not take more than a few minutes. The important thing to remember here is that, if you have to recreate a service, there is no way to back up and restore data—if you make mistakes here, everything has to be done from scratch.
The reason to recreate would be changing the datatypes or other search attributes of the search index columns. While it will not be a problem during this exercise, have that in mind when creating a production workload.
