Script or command to search strings on multiple folders and output result to /tmp

I was searching strings on the archive using this command.. zgrep 'order-number' *fastbg* > /tmp/order-number.fastbg.txt

How can I search on multiple dated directories (20210302, 20210303, 20210304..) using a script or find command. I still want to output result on /tmp. Can anyone help?
