MemoryRouter does not set search part of location

I want to test if my component can get search part of location and transform to json for use, but when I set initialEntries with the querystring the search part is not changed.

//My Test
render(
  <MemoryRouter inititalEntries={['/pesquisa?number=1&uf=PR']}>
    <App/>
  </MemoryRouter>
)

//My Component
const Pesquisa = (props) => {
  const { search } = props.location
  // what i want
  // search === '?number=1&uf=PR'
  // what i have
  // search === ''
}
export default withRouter(Pesquisa)

// My Container App
const App = () => 
  <div className="App">
    <BrowserRouter>
      <Switch>
        <Route path="/pesquisa" render={props => <Pesquisa/>}/>
      </Switch>
    </BrowserRouter>
  </div>
