Source for writing DataTables compatible regular expressions?

Hello, I am implementing the example shown here https://datatables.net/examples/api/regex.html, and am curious about the regex syntax that is accepted. My first guess was maybe just Javascript regex, but it seems only some of the examples at this link work https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions , or I'm not understanding. Before hitting my head against the wall too much, I was hoping someone could confirm what syntax I should be using? Thanks!
