How to specify regex in istio's uri

Question

Expectations.

• /hoge/?xxx=xxx Transition the above PATH to port xxxx

Current configuration

  http:
    - match:
        - uri:
            regex: '\/hoge\/\?.*$'
          port: xxxx

What's happening.

Regex is not working. I thought about using queryParams, but it is not configured because some keys are present and some are not. How can I get regex to work?

What we tried.

• /hoge/?.*$
• "/hoge/?.*$"
• /hoge/?
