How to match custom parameters format

How to use HashRouter to match custom parameters format below format?

> https://domain/user_id=123#app/products/food&min_price=10&max_price=2000

Our company uses strange parameters food&min_price=10&max_price=2000
Ideally, it should follow the standard like

food?min_price=10&max_price=2000

however, this existing format could not be changed due to the legacy and used by a lot of customers. Any idea to make the routes working with this odd custom parameters? and let this route could be matched <Route path={food} element={FoodView}/>

<HashRouter basename={`app`}>
    <Routes>        
        <Route
            path={`products`}
        >
            <Route
                path={`food`}
                element={<FoodView/>}/>
            <Route
                path={`computer`}
                element={<ComputerView/>}/>
        </Route>        
    </Routes>
</HashRouter>
