Mute gzip errors/warnings when using zgrep

Question

I frequently use the commands like

find . ! -iname "*test*" -o -iname "*foo*" | xargs zgrep -ie first.*last -e last.*first

I use zgrep because it can grep through .gz files, and if the files aren't gzipped it simply uses grep. However I frequently get

gzip: copy.txt.gz: No such file or directory

logs that clutter the output of my searches. Is there any way to mute these gzip logs?

You can redirect the command standard error output to the null device.

find . ! -iname "*test*" -o -iname "*foo*" | xargs zgrep -ie first.*last -e last.*first 2>/dev/null
