An example virtual service:

apiVersion: gateway.solo.io/v1
kind: VirtualService
metadata:
  name: test-query-parameter
  namespace: gloo-system
spec:
  virtualHost:
    domains:
      - 'foo'
    routes:
      - matcher:
          queryParameters:
            - name: param1
              value: value1
            - name: param2
            - name: param3
              regex: true
              value: "[a-z]{1}"
          prefix: /
        routeAction:
          single:
            upstream:
              name: json-upstream
              namespace: gloo-system
