Further reading
Indexes are an advanced topic and should be created carefully as these may impact the system’s performance negatively and drastically. I would suggest further reading for a deeper understanding, and that you should first create these in dev and test and observe how they impact the performance of the query and the system overall.
For a deeper understanding, take a look at the Microsoft book here: https://learn.microsoft.com/en-us/sql/relational-databases/indexes/indexes?view=sql-server-ver16.
