Is your feature request related to a problem? Please describe.

When using a multi-value query string parameter only the first value is checked.

Url ENDPOINT?sections=90&sections=130 with this check:

r.Queries("sections", "130")

It doesn't match, and it should because the only key-value required matches, but as it only checks the first it encounters (sections=90 in this case), it determines it doesn't match.
getURLQuery() only looks for the first query key: findFirstQueryKey().

Describe the solution that you would like.

Multi-value query params like sections=90&sections=130 should be matched by both commands from below, regardless of the order in the query string:

r.Queries("sections", "130")
r.Queries("sections", "90", "sections", "130")

Describe alternatives you have considered.
