Yes, you can search for specific customers in sales by customer detail report, Fushies. I'd be glad to share with you the steps to achieve this.

Here's how to display one specific customer in Modern view:

1. Go to the Reports menu, and choose Sales by customer detail in the Find report by name dropdown.
2. Click Filter, in Filter by dropdown, select Customer, and in the option dropdown, select Equals.
3. In the "Value" dropdown, choose the specific customer you wish to pull up. Then, click the Add filter button.
   
   

While in Classic view, here's how:

2. Click the Customize button, Go to the Filter dropdown, and select the specific customer you wish to pull up.
3. Then, the Run report button.
