Contains word exact string?

[yakagami]

The Docs say:

the object of ql:contains-word can be a string with several keywords. The keywords are treated as a bag of words, not as a phrase. That is, they can occur in the text record in any order

How can one search for an exact phrase that includes spaces? For example, text that is exactly "Unreal Engine 5"? I have linked an example query where I am trying to use this. In the linked query, some text matches are "Unreal Engine 5" while others contains those three words separately.
