Let's take this application as example:

The query parameter `q` is of type `str | None`, that means that it's of type `str` but could also be `None`, and indeed, the default value is `None`, so FastAPI will know it's not required.

  `Do you mean that you think you can find out the answer to it?'
said the March Hare.

  `Exactly so,' said Alice.

  `Then you should say what you mean,' the March Hare went on.

  `I do,' Alice hastily replied; `at least--at least I mean what
I say--that's the same thing, you know.'
