How can I create a filtered deck with only one deck whilst also using "is:due prop:due>-7" from the Anki Manual?

To catch up with an anki deck, I want to create a filtered deck.

I have followed the advice at Filtered Decks (ankiweb.net) and have put “is:due prop:due>-7” into the search function with the name of the home deck where the cards are coming from as shown here: deck: "Chinese Lesson 27 is:due prop:due>-7"

This did not work. A box popped up reading, “The provided search did not match any cards. Would you like to revise it?”

Thank you!

You have the (") in the wrong place.

Presumably you want

deck:"Chinese Lesson 27" is:due prop:due>-7

Note the space after the colon was also removed.
