How do you chain GREP patterns in InDesign?

[JasonDD210]

In regex, I can use this to highlight quotation marks:

"([^"]*)"

And if I want to add another pattern, and can use the pipe symbol like this:

\b("([^"]*)"|'([^']*)')\b

This will match single and double quotes. However this syntax with the pipe doesn't seem to work in InDesign.How can I get this to work?

I can't edit the obvious mistake out, so here's the question again, without the mistake that I am not allowed to correct:

You can put them together in a single class as literals: ['"]
