I was trying to figure out how the "Pages in these categories" search operates, so read the pop-up Help panel (see screenshot below). The instructions say "Only the first 5 subcategories will be considered in your search."
I debated the meaning of this with colleagues in the office; most thought it meant exactly what it says—that only 5 subcategories will be included in the search. However, a look at the [[ https://en.wikipedia.org/wiki/Help:Searching#deepcategory: | Help doc for Searching Wikipedia ]] makes clear that that is not the meaning. The doc says "The depth of the tree is currently limited to 5 //levels//." [emphasis added].
To make the help panel clearer for English speakers, I suggest you change the wording as follows: "Only the first 5 subcategory levels will be included in your search."
