Hi George, depending on version it may be different. Have a look at this link https://support.office.com/en-us/article/Understanding-query-rules-8ca2588d-9dc7-45aa-90a4-428d4d695d07?ui=en-US&rs=en-US&ad=US
At the bottom you’ll see two links that show you how to manage your query rules. This can be done in Site Collection Administration Settings, under a node called “Search Query Rules”
Can you answer these?
