Regex file name match issue

[Temptech]

When I search for rar or zip format files with the word "AHK" using regular expressions, it doesn't seem to work. Is my expression written incorrectly? Or does the software itself not support this writing style?
Here is my regular expression, which seems unable to search for file names from multiple specified extensions. Can someone help me fix it?

regex:.*AHK.*\.(rar|zip)$

[void]

If you are using Everything 1.4, please escape the | with double quotes (")

For example:

regex:".*AHK.*\.(rar|zip)$"

| = OR in Everything.
"" = escape Everything operators

Thank you very much, it works.
